Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, `ast_loggrabber` executes a `Python script` from the world-writable `/tmp` directory. An attacker already authorized to open a shell session on the Asterisk server may place a malicious script there and gain elevated privileges or execute code when an administrator runs `ast_loggrabber` as a user with elevated privileges. 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":"2026-10-27T21:48:40.078+00:00","modifiedAt":"2026-10-29T18:22:00.568+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 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/asterisk/asterisk/security/advisories/GHSA-xgj6-2gc5-5x9c","https://github.com/asterisk/asterisk/commit/022407ec47adebe27b7ec8bcf5626e5a02fe1551","https://github.com/asterisk/asterisk/commit/a51c4e3d6bccce4bc4226c43e78952573a62f165","https://github.com/asterisk/asterisk/commit/ba8e5bdecd5280fc0ab230df59e41ea21b3a052f","https://github.com/asterisk/asterisk/commit/bd63fe121d0e86867863bd98b5771e592273b035","https://github.com/asterisk/asterisk/commit/c0fc2ae54cb6289a48a80333432f5fdf5a40c7de","https://github.com/asterisk/asterisk/commit/f18ac4c964781f671e400342790bf40679698067","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-2026-57203","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-57203","identifiers":["CVE-2026-57203"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
