{"cve":"CVE-2026-57190","nvd":{"published":"2026-10-27T22:17:27.197","modified":"2026-10-27T22:17:27.197","status":"Received","description":"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 20.7-cert11, 22.8-cert3, the `PostgreSQL` and `TDS/MSSQL` Channel Event Log backends `cel_pgsql` and `cel_tds` may permit arbitrary SQL execution when untrusted data is set in the CEL `eventtype` column by the `CELGenUserEvent` dialplan application. The `cel_pgsql` or `cel_tds` backend must be loaded and configured, and the administrator must call `CELGenUserEvent` in the dialplan without ensuring that only valid data is passed to the application. 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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:H/SI:L/SA:L","score":7.0},"cvss_v3":null,"cwes":["CWE-89"],"references":["https://github.com/asterisk/asterisk/commit/046a8b0b50623d80926c1adc2eca1c9c17e258ed","https://github.com/asterisk/asterisk/commit/0a86e45e8cde7630276f8363de45f71d1635d2f4","https://github.com/asterisk/asterisk/commit/88c65757b56c716b5a175f35941be22e038b256f","https://github.com/asterisk/asterisk/commit/8bf7746d01221d6d2bcfcd46ba7a1cff066a1a8b","https://github.com/asterisk/asterisk/commit/8cb6dfd41debb2259ec3a33ccfa78f1d902e4c22"],"products":[],"source":"nvd","synced_at":"2026-10-27T22:38:42.705297859+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
