> U.S. CISA adds GitLab and Cisco flaws to its Known Exploited Vulnerabilities catalog

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds GitLab and Cisco flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added GitLab and Cisco vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog: Below are the flaws added to the catalog: CVE-2026-97229 (CVSS score of 10.0) GitLab Community Edition and Enterprise Edition Integer Overflow or Wraparound vulnerability CVE-2026-76418 (CVSS score of 8.6) Cisco Secure Firewall ASA Software and Cisco Secure FTD Software Unchecked Return Value to NULL Pointer Dereference Vulnerability CVE-2026-97229 is a critical security flaw that could let attackers run code on its servers without logging in. The flaw affects Community Edition (CE) and Enterprise Edition (EE), it is an integer overflow bug caused by weak validation of regular expressions in CI/CD configurations. The issue affects GitLab versions 19.2 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2. Users should upgrade to a patched version to protect their systems. GitLab advisory “GitLab has remediated an issue that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation.” reads the advisory. The researchers joaxcar reported this vulnerability through the company’s HackerOne bug bounty program. Alpine Linux recently reported that an unknown attacker tried to exploit the vulnerability against Alpine Linux on October 20 and 21, 2026, but the attempts failed. CVE-2026-76418 is a NULL pointer dereference vulnerability affecting Cisco Secure Firewall ASA and FTD Software. It could allow an unauthenticated remote attacker to force a device to reload, causing a denial-of-service (DoS) condition. Cisco said it became aware of active exploitation earlier this month. The company has not disclosed who is behind the attacks, how many organizations have been targeted, or what attackers may have done after gaining access. According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the two vulnerabilities by November 1st, 2026. Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, CISA)
