{"id":"UBUNTU-CVE-2026-57190","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 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.","modified":"2026-10-28T20:17:23.802986054Z","published":"2026-10-27T22:17:00Z","upstream":["CVE-2026-57190"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57190"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57190"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-ph27-3m5q-mj5m"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/046a8b0b50623d80926c1adc2eca1c9c17e258ed"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/0a86e45e8cde7630276f8363de45f71d1635d2f4"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/88c65757b56c716b5a175f35941be22e038b256f"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/8bf7746d01221d6d2bcfcd46ba7a1cff066a1a8b"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/8cb6dfd41debb2259ec3a33ccfa78f1d902e4c22"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/a04bee3992c28e1681457370e46f30494b7c6619"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/ff21d90e61d199db9b963c671d125a1e917d41ac"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1"}],"affected":[{"package":{"name":"asterisk","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/asterisk?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:13.1.0~dfsg-1.1ubuntu3","1:13.1.0~dfsg-1.1ubuntu4","1:13.1.0~dfsg-1.1ubuntu4.1","1:13.1.0~dfsg-1.1ubuntu4.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"asterisk","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-config","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-dahdi"},{"binary_name":"asterisk-mobile","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-modules"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-mp3"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-mysql"},{"binary_name":"asterisk-ooh323","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-voicemail"},{"binary_name":"asterisk-voicemail-imapstorage","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-voicemail-odbcstorage","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-vpb","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57190.json"}},{"package":{"name":"asterisk","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/asterisk?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:13.17.2~dfsg-1ubuntu1","1:13.17.2~dfsg-2ubuntu1","1:13.18.1~dfsg-1ubuntu1","1:13.18.3~dfsg-1ubuntu1","1:13.18.3~dfsg-1ubuntu2","1:13.18.3~dfsg-1ubuntu3","1:13.18.3~dfsg-1ubuntu4"],"ecosystem_specific":{"binaries":[{"binary_name":"asterisk","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-config"},{"binary_name":"asterisk-dahdi","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-mobile","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-modules"},{"binary_name":"asterisk-mp3","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-mysql","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-ooh323"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-tests"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-voicemail"},{"binary_name":"asterisk-voicemail-imapstorage","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-voicemail-odbcstorage","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-vpb","binary_version":"1:13.18.3~dfsg-1ubuntu4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57190.json"}},{"package":{"name":"asterisk","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/asterisk?arch=source&dis
