Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 22.8-cert3, an authenticated attacker with read-only permissions for the `Asterisk REST Interface (ARI)` may, under certain conditions, execute write operations through `REST-over-WebSocket`. The authorization bypass permits `arbitrary module path` loading and conditional remote code execution. The Asterisk HTTP web server must be enabled and reachable, and the attacker must already have valid `read-only ARI credentials`. HTTP is disabled by default and binds only to 127.0.0.1 by default even when enabled. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 22.8-cert3."}], "lastModified": "2026-10-30T21:17:12.537", "sourceIdentifier": "security-advisories@github.com"}
