CVE-2026-20230
Actively exploited (CISA KEV) - patch before 2026-06-28
Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) contain a server-side request forgery (SSRF) Vulnerability that could allow an unauthenticated, remote attacker to write files to the underlying operating system that could be used later to elevate to root.
Actively exploited in the wild and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: No fix is published yet for an actively-exploited flaw. Apply vendor mitigations, restrict exposure, and watch for a patch.
Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
