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.","severity":"high","score":7.5,"published":"2026-10-27T21:13:03.777Z","modified":"2026-10-27T21:13:03.777Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-wcvv-g26m-wx5c","https://github.com/asterisk/asterisk/commit/051d29a0d35559e9165bab346de9422e25415533","https://github.com/asterisk/asterisk/commit/205c301a0a0b0d013d4ebdf12856ebbc30405350","https://github.com/asterisk/asterisk/commit/762b4c9c39b28fa5564112b0f484012298469a6c","https://github.com/asterisk/asterisk/commit/87641e9b2cd62c998c5283400ba77b61b5b07dd4","https://github.com/asterisk/asterisk/commit/9d198a7d16ccba51507dfea6c1ecc511e89d698a","https://github.com/asterisk/asterisk/commit/c10cdbce072a708060cd38a89d6850808fe6bf46","https://github.com/asterisk/asterisk/releases/tag/20.20.1","https://github.com/asterisk/asterisk/releases/tag/21.12.3","https://github.com/asterisk/asterisk/releases/tag/22.10.1","https://github.com/asterisk/asterisk/releases/tag/23.4.1","https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","https://github.com/asterisk/asterisk/tree/24.0.0-pre1"],"sources":[{"name":"CVE","id":"CVE-2026-57200","modified":"2026-10-27T21:13:03.777Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-57200"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T09:10:39.623Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
