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.

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 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 CTEK Chargeportal are affected: Chargeportal vers:all/* CVSS Vendor Equipment Vulnerabilities v3 9.4 CTEK CTEK Chargeportal 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: Sweden Vulnerabilities Expand All + CVE-2026-25192 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.

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.
