CISA Adds Five Exploited Vulnerabilities to KEV Catalog Including AhsayCBS Authentication and Command Injection Flaws
The US Cybersecurity and Infrastructure Security Agency (CISA) has added five vulnerabilities to its Known Exploited Vulnerabilities catalog after confirming active exploitation in the wild. Four vulnerabilities were registered on October 14, 2026, and one additional entry followed on October 15. Among the newly listed issues are two critical flaws affecting the AhsayCBS backup management server: CVE-2026-105133, an authentication bypass in the API, and CVE-2026-105134, a command injection vulnerability in the replication feature. When chained together, the pair allows unauthenticated remote attackers to execute arbitrary operating system commands. Vendor Ahsay has released hotfixes in versions 10.3.4.45 and 9.15.2.70 because standard patches cannot fully address the issues. The advisory also references vulnerabilities in Atlassian products and multiple network security solutions from other vendors.
