🚨 Cisco just updated its advisory: a major security issue in Cisco Unified CM / Unified CM SME—CVE-2026-20230—is being actively exploited in the wild. CISA has now added it to the KEV (Known Exploited Vulnerabilities) catalog. With a CVSS 8.6 severity rating, this is a “patch ASAP” situation. This is an SSRF (Server-Side Request Forgery) flaw. In plain terms: the affected system can be tricked into making requests to attacker-controlled destinations. That can open the door for follow-on attacks—exfiltration, unexpected network calls, and deeper compromise. Cisco initially said there was public PoC code but no proof of real exploitation. Then it escalated fast: Defused Cyber first observed exploitation attempts on June 22, and CISA confirmed evidence of active exploitation by June 25, triggering KEV inclusion. Cisco’s fix: upgrade to the patched branches—“14SU6” and “15SU5” (15SU5 expected in September). If you can’t upgrade yet, use Cisco’s temporary mitigations. Today’s priorities: verify your current Unified CM/SME version, apply the patch or mitigation, and tighten log monitoring and exposure review. #CyberSecurity #Cisco #VulnerabilityManagement #SSRF #KEV #IncidentResponse
