CVE-2026-20362 | Cisco Finesse Server-Side Request Forgery Vulnerability
CVE-2026-20362 is an unauthenticated server-side request forgery in Cisco Finesse (CVSS 3.1 score 7.2), found by Horizon3 researchers Noah King and Brandon Peterson. The embedded Apache Shindig content proxy fetches attacker-supplied URLs, including loopback services such as the Finesse REST API at 127.0.0.1:8082, which returns SystemInfo with node hostnames and the XMPP domain. Cisco published its advisory on 7 October 2026. Fixes are planned for January and February 2027, and no workaround exists.
