CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-20131 Cisco Secure Firewall Management Center (FMC) Software and Cisco Security Cloud Control (SCC) Firewall Management Deserialization of Untrusted Data 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.

View CSAF Summary Successful exploitation of these vulnerabilities could enable attackers to gain unauthorized administrative control over vulnerable charging stations or disrupt charging services through denial-of-service attacks. 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.

In episode 459 of Smashing Security, we dive into a chillingly clever account takeover attempt targeting WordPress co-founder Matt Mullenweg - involving MFA fatigue, real Apple alerts, a convincing support call, and a phishing page that oh-so-nearly worked. If a famous techie could have this happen to you, can you be sure you're immune? Plus: would you donate your lifetime medical history to science if you were promised anonymity? We unpack serious concerns around UK Biobank, where “de-identified” data may not be as anonymous as you think — and how surprisingly little information it takes to reveal everything. And! Human-powered “AI”, and a punishment worse than prison: eight hours on the RSA expo floor... All this, and much more, in episode 459 of the "Smashing Security" podcast with cybersecurity veteran Graham Cluley, and special guest Paul Ducklin.

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-20963 Microsoft SharePoint Deserialization of Untrusted Data 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.

CISA is aware of malicious cyber activity targeting endpoint management systems of U.S. organizations based on the March 11, 2026 cyberattack against U.S.-based medical technology firm Stryker Corporation, which affected their Microsoft environment.1 To defend against similar malicious cyber activity, CISA urges organizations to harden endpoint management system configurations using the recommendations and resources provided in this alert. CISA is conducting enhanced coordination with federal partners, including the Federal Bureau of Investigation (FBI), to identify additional threats and determine mitigation actions. To defend against similar malicious activity that misuses legitimate endpoint management software, CISA urges organizations to implement Microsoft’s newly released best practices for securing Microsoft Intune; the principles of these recommendations can be applied to Intune and more broadly to other endpoint management software: Use principles of least privilege when designing administrative roles. Leverage Microsoft Intune’s role-based access control (RBAC) to assign the minimum permissions necessary to each role for completing day-to-day operations—permissions include what actions the role can take, and what users and devices it can apply that action to. Enforce phishing-resistant multi-factor authentication (MFA) and privileged access hygiene. Use Microsoft Entra ID capabilities (including Conditional Access, MFA, risk signals, and privileged access controls) to block unauthorized access to privileged actions in Microsoft Intune. Configure access policies to require Multi Admin Approval in Microsoft Intune. Set up policies that require a second administrative account’s approval to allow changes to sensitive or high-impact actions (such as device wiping), applications, scripts, RBAC, configurations, etc. Additionally, CISA recommends reviewing the following resources to strengthen defenses against similar malicious cyber activity: Microsoft resources: For recommendations on securing Microsoft Intune, see Best practices for securing Microsoft Intune. For guidance on implementing Multi Admin Approval in Microsoft Intune, see Use Access policies to implement Multi Admin Approval. For recommendations on configuring Microsoft Intune using zero trust principles, see Configure Microsoft Intune for increased security. For guidance on implementing Microsoft Intune RBAC policies, see Role-based access control (RBAC) with Microsoft Intune. For guidance on deploying Privileged Identity Management (PIM) across Microsoft Intune, Entra ID, and other Microsoft software, see Plan a Privileged Identity Management deployment. CISA resources: For guidance on implementing phishing-resistant multifactor authentication (MFA), see Implementing Phishing-Resistant MFA.
