Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an authenticated attacker may crash Asterisk through a buffer over-read in the `PJSIP MWI body parser` by sending a carefully crafted `SIP NOTIFY` request. The attacker must pass SIP authentication using either a username/password or `source IP address matching`. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.","state":0,"publishedAt":"2026-10-27T16:40:27.615+00:00","modifiedAt":"2026-10-27T16:40:27.615+00:00","affected":[{"ecosystem":"Vendor product","name":"asterisk","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"asterisk\",\n                    \"product\": \"asterisk\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 20.20.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 21.0.0-pre1, < 21.12.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 22.0.0-pre1, < 22.10.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 23.0.0-pre1, < 23.4.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"certified-asterisk","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"asterisk\",\n                    \"product\": \"certified-asterisk\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 20.7-cert11\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 22.8-cert1-pre1, < 22.8-cert3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-8jw3-ccr9-xrmf","https://github.com/asterisk/asterisk/commit/07aec894a1fdfa7fa989d3ab40fdf0dcda8005bb","https://github.com/asterisk/asterisk/commit/1039bed76fa3248f58b6880e4b3f1421ef98b01f","https://github.com/asterisk/asterisk/commit/1b2d99d8eb9206d37fd47115996f67fd28bd056f","https://github.com/asterisk/asterisk/commit/3100a0d331affbf0995b8c57aaddb31cf3971f6e","https://github.com/asterisk/asterisk/commit/57ce484a45b098de417f19265c95c64497782e36","https://github.com/asterisk/asterisk/commit/919f2ffda03329c9014bedcb3c7789d38660c9ed","https://github.com/asterisk/asterisk/commit/dafff9fb60281817225f1ce6371a5aa2fbb967a4","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-20.7-cert11","https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","https://github.com/asterisk/asterisk/tree/24.0.0-pre1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-57185","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57185","identifiers":["CVE-2026-57185"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
