{"schema":"threatline.record/2","record":{"id":"CVE-2026-57200","aliases":["GHSA-wcvv-g26m-wx5c"],"summary":"Asterisk: ARI REST-over-WebSocket read-only bypass allows arbitrary module path load and conditional RCE","details":"Asterisk is an open source private branch exchange and telephony toolkit. 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.","categories":["Unclassified"],"product":"asterisk","vendor":"asterisk","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57200","source_modified_at":"2026-10-27T21:13:03.777Z","fetched_at":"2026-10-28T01:10:53.534015Z","product":"asterisk","vendor":"asterisk","versions":[{"version":"< 20.20.1","status":"affected"},{"version":">= 21.0.0-pre1, < 21.12.3","status":"affected"},{"version":">= 22.0.0-pre1, < 22.10.1","status":"affected"},{"version":">= 23.0.0-pre1, < 23.4.1","status":"affected"}],"defaultStatus":null},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57200","source_modified_at":"2026-10-27T21:13:03.777Z","fetched_at":"2026-10-28T01:10:53.534015Z","product":"certified-asterisk","vendor":"certified-asterisk","versions":[{"version":">= 22.8-cert1-pre1, < 22.8-cert3","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T21:13:03.777Z","modified_at":"2026-10-27T21:13:03.777Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57200","fetched_at":"2026-10-28T01:10:53.534015Z","source_modified_at":"2026-10-27T21:13:03.777Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-wcvv-g26m-wx5c","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/051d29a0d35559e9165bab346de9422e25415533","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/205c301a0a0b0d013d4ebdf12856ebbc30405350","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/762b4c9c39b28fa5564112b0f484012298469a6c","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/87641e9b2cd62c998c5283400ba77b61b5b07dd4","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/9d198a7d16ccba51507dfea6c1ecc511e89d698a","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/c10cdbce072a708060cd38a89d6850808fe6bf46","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T21:13:03.777Z","content_hash":"076aef463643fe9a95efd0e3bb11144f83b90df29d970bb2eeee62b952ee3d16"}}
