CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-33017 Langflow Code Injection Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

Sen. Ron Wyden is warning us of an abuse of Section 702: Wyden took to the Senate floor to deliver a lengthy speech, ostensibly about the since approved (with support of many Democrats) nomination of Joshua Rudd to lead the NSA. Wyden was protesting that nomination, but in the context of Rudd being unwilling to agree to basic constitutional limitations on NSA surveillance. But that’s just a jumping off point ahead of Section 702’s upcoming reauthorization deadline. Buried in the speech is a passage that should set off every alarm bell: There’s another example of secret law related to Section 702, one that directly affects the privacy rights of Americans. For years, I have asked various administrations to declassify this matter. Thus far they have all refused, although I am still waiting for a response from DNI Gabbard. I strongly believe that this matter can and should be declassified and that Congress needs to debate it openly before Section 702 is reauthorized. In fact, when it is eventually declassified, the American people will be stunned that it took so long and that Congress has been debating this authority with insufficient information. Over the decades, we have learned to take Wyden’s warnings seriously.

A reboot is required for workstations and servers. Depending on the existing system version, online upgrade without production interruption might be possible. Schneider Electric recommends you work with your local field service representative or technical service consultant for further information. https://buyautomation.se.com/ Mitigation If users choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit: The vulnerability is attacked with manipulated data from external sources to the DCS computers. Examples for these are: * Configuration taglists * DirectAccess Scripts * Any partial or full Galaxy backups * Library files * Code snippets * ASCII files of any sort * Generally, any file getting from outside the DCS computer on a DCS computer. Only use data from trusted sources, check for correct file name endings on data files, check for reasonable file sizes for any files coming to the system, and check structured data for any fields or columns which might be unexpected. Check for unusual manipulations of data within data files and reject files containing unexpected data or structures. Use secure communication channels and encrypt communications when communicating outside the site network. Avoid and ban removable media (e.g. USB sticks or drives) Minimize count of users with engineering or administrative rights to DCS computers and ensure all interactions on DCS computers are executed with minimal user access rights. Consequently, isolating Foxboro DCS computers will help minimizing the risk of this vulnerability being exploited.

Japan’s election last month and the rise of the country’s newest and most innovative political party, Team Mirai, illustrates the viability of a different way to do politics. In this model, technology is used to make democratic processes stronger, instead of undermining them. It is harnessed to root out corruption, instead of serving as a cash cow for campaign donations. Imagine an election where every voter has the opportunity to opine directly to politicians on precisely the issues they care about. They’re not expected to spend hours becoming policy experts. Instead, an AI Interviewer walks them through the subject, answering their questions, interrogating their experience, even challenging their thinking. Voters get immediate feedback on how their individual point of view matches—or doesn’t—a party’s platform, and they can see whether and how the party adopts their feedback. This isn’t like an opinion poll that politicians use for calculating short-term electoral tactics. It’s a deliberative reasoning process that scales, engaging voters in defining policy and helping candidates to listen deeply to their constituents. This is happening today in Japan. Constituents have spent about eight thousand hours engaging with Mirai’s AI Interviewer since 2025. The party’s gamified volunteer mobilization app, Action Board, captured about 100,000 organizer actions per day in the runup to last week’s election. It’s how Team Mirai, which translates to ‘The Future Party,’ does politics. Its founder, Takahiro Anno, first ran for local office in 2024 as a 33 year old software engineer standing for Governor of Tokyo. He came in fifth out of 56 candidates, winning more than 150,000 votes as an unaffiliated political outsider. He won attention by taking a distinctive stance on the role of technology in democracy and using AI aggressively in voter engagement. Last year, Anno ran again, this time for the Upper Chamber of the national legislature—the Diet—and won. Now the head of a new national party, Anno found himself with a platform for making his vision of a new way of doing politics a reality. In this recent House of Representatives election, Team Mirai shot up to win nearly four million votes. In the lower chamber’s proportional representation system, that was good enough for eleven total seats—the party’s first ever representation in the Japanese House—and nearly three times what it achieved in last year’s Upper Chamber election. Anno’s party stood for election without aligning itself on the traditional axes of left and right. Instead, Team Mirai, heavily associated with young, urban voters, sought to unite across the ideological spectrum by taking a radical position on a different axis: the status quo and the future. Anno told us that Team Mirai believes it can triple its representation in the Diet after the next elections in each chamber, an ostentatious goal that seems achievable given their rapid rise over the past year. In the American context, the idea of a small party unifying voters across left and right sounds like a pipe dream. But there is evidence it worked in Japan. Team Mirai won an impressive 11% of proportional representation votes from unaffiliated voters, nearly twice the share of the larger electorate. The centerpiece of the party’s policy platform is not about the traditional hot button issues, it’s about democracy itself, and how it can be enhanced by embracing a futuristic vision of digital democracy. Anno told us how his party arrived at its manifesto for this month’s elections, and why it looked different from other parties’ in important ways. Team Mirai collected more than 38,000 online questions and more than 6,000 discrete policy suggestions from voters using its AI Policy app, which is advertised as a ‘manifesto that speaks for itself.’ After factoring in all this feedback, Team Mirai maintained a contrarian position on the biggest issue of the election: the sales tax and affordability. Rather than running on a reduction of the national sales tax like the major parties, Team Mirai reviewed dozens of suggestions from the public and ultimately proposed to keep that tax level while providing support to families through a child tax credit and lowering the required contribution for social insurance. Anno described this as another future-facing strategy: less price relief in the short term, but sustained funding for essential programs. Anno has always intended to build a different kind of party. After receiving roughly $1 million in public funding apportioned to Team Mirai based on its single seat in the Upper Chamber last year, Anno began hiring engineers to enhance his software tools for digital democracy. Anno described Team Mirai to us as a ‘utility party;’ basic infrastructure for Japanese democracy that serves the broader polity rather than one faction. Their Gikai (‘assembly’) app illustrates the point. It provides a portal for constituents to research bills, using AI to generate summaries, to describe their impacts, to surfacing media reporting on the issue, and to answer users’ questions. Like all their software, it’s open source and free for anyone, in any party, to use. After last week’s victory, Team Mirai now has about $5 million in public funding and ambitions to grow the influence of their digital democracy platform. Anno told us Team Mirai has secured an agreement with the LDP, Japan’s dominant ruling party, to begin using Team Mirai’s Gikai and corruption-fighting Mirumae financial transparency tool. AI is the issue driving the most societal and economic change we will encounter in our lifetime, yet US political parties are largely silent. But AI and Big Tech companies and their owners are ramping up their political spending to influence the parties. To the extent that AI has shown up in our politics, it seems to be limited to the question of where to site the next generation of data centers and how to channel populist backlash to big tech. Those are causes worthy of political organizing, but very few US politicians are leveraging the technology for public listening or other pro-democratic purposes. With the midterms still nine months away and with innovators like Team Mirai making products in the open for anyone to use, there is still plenty of time for an American politician to demonstrate what a new politics could look like. This essay was written with Nathan E. Sanders, and originally appeared in Tech Policy Press.

It’s an impressive feat, over a decade after the box was released: Since reset glitching wasn’t possible, Gaasedelen thought some voltage glitching could do the trick. So, instead of tinkering with the system rest pin(s) the hacker targeted the momentary collapse of the CPU voltage rail. This was quite a feat, as Gaasedelen couldn’t ‘see’ into the Xbox One, so had to develop new hardware introspection tools. Eventually, the Bliss exploit was formulated, where two precise voltage glitches were made to land in succession. One skipped the loop where the ARM Cortex memory protection was setup. Then the Memcpy operation was targeted during the header read, allowing him to jump to the attacker-controlled data. As a hardware attack against the boot ROM in silicon, Gaasedelen says the attack in unpatchable. Thus it is a complete compromise of the console allowing for loading unsigned code at every level, including the Hypervisor and OS. Moreover, Bliss allows access to the security processor so games, firmware, and so on can be decrypted.

CISA has added five new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2025-31277 Apple Multiple Products Buffer Overflow Vulnerability CVE-2025-32432 Craft CMS Code Injection Vulnerability CVE-2025-43510 Apple Multiple Products Improper Locking Vulnerability CVE-2025-43520 Apple Multiple Products Classic Buffer Overflow Vulnerability CVE-2025-54068 Laravel Livewire Code Injection Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

CISA and the Federal Bureau of Investigation released a Public Service Announcement (PSA) warning about ongoing phishing campaigns by cyber actors associated with the Russian Intelligence Services targeting commercial messaging applications (CMAs). These campaigns aim to bypass encryption to compromise to individual user accounts with targets including current and former U.S. government officials, military personnel, political figures, and journalists. Evidence shows that cyber actors have been able to compromise individual CMA accounts, but not encryption of the applications themselves. The actors’ global campaigns have resulted in unauthorized access to thousands of individual CMA accounts to view the victims’ messages and contact lists, send messages, and conduct additional phishing against other CMA accounts. CISA and FBI urge CMA users to review the PSA, follow recommended cybersecurity practices, and remain vigilant for suspicious activity.

404 Media has a story about Proton Mail giving subscriber data to the Swiss government, who passed the information to the FBI. It’s metadata—payment information related to a particular account—but still important knowledge. This sort of thing happens, even to privacy-centric companies like Proton Mail.

The following versions of IGL-Technologies eParking.fi are affected: eParking.fi vers:all/* CVSS Vendor Equipment Vulnerabilities v3 9.4 IGL-Technologies IGL-Technologies eParking.fi Missing Authentication for Critical Function, Improper Restriction of Excessive Authentication Attempts, Insufficient Session Expiration, Insufficiently Protected Credentials Background Critical Infrastructure Sectors: Energy, Transportation Systems Countries/Areas Deployed: Worldwide Company Headquarters Location: Finland Vulnerabilities Expand All + CVE-2026-29796 WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend. View CVE Details Affected Products IGL-Technologies eParking.fi Vendor: IGL-Technologies Product Version: IGL-Technologies eParking.fi: vers:all/* Product Status: known_affected Remediations Mitigation IGL-Technologies has updated eParking's OCPP servers to reduce the risks posed by the vulnerability. These updates implemented the following security controls: 1) Enforce modern security profiles and stronger authentication. 2) Device‑level whitelisting was implemented to ensure that only authorized charging units can connect. 3) Rate‑limiting controls prevent excessive requests and reduces DoS risk. 4) Enhanced automated monitoring and alerting to detection abnormal network activity. Devices using the encrypted deployment of eParking's OCPP servers or IGL-Technologies proprietary eTolppa protocol are not impacted by these vulnerabilities. Mitigation To prevent this in the future IGL-Technologies will continue vulnerability monitoring under their ISO 27001:2022 security program and tighten security requirements for future third‑party OCPP hardware approvals.

This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
