In Asterisk prior to versions 18.20.1, 20.5.1, and 21.0.1, as well as certified-asterisk prior to 18.9-cert6, it is possible to read any arbitrary file even when the `live_dangerously` is not enabled. This allows arbitrary files to be read. Asterisk versions 18.20.1, 20.5.1, and 21.0.1, as well as certified-asterisk prior to 18.9-cert6, contain a fix for this

In Asterisk prior to versions 18.20.1, 20.5.1, and 21.0.1, as well as certified-asterisk prior to 18.9-cert6, it is possible to read any arbitrary file even when the `live_dangerously` is not enabled. This allows arbitrary files to be read. Asterisk versions 18.20.1, 20.5.1, and 21.0.1, as well as certified-asterisk prior to 18.9-cert6, contain a fix for this issue.","status":"published","published":"2023-12-14T20:15:00Z","modified":"2026-10-17T12:56:26.248884829Z","cvss":[{"version":"3.1","score":4.9,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","level":"medium"},{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","level":"high"}],"updated_at":"2026-11-02T16:54:23.935133Z"},{"id":"DLA-3696-1","title":"asterisk - security update","status":"published","published":"2023-12-28T00:00:00Z","modified":"2026-03-09T01:21:20.606713Z","updated_at":"2026-11-02T15:46:12.203458Z"},{"id":"DSA-5596-1","title":"asterisk - security update","status":"published","published":"2024-01-04T00:00:00Z","modified":"2026-03-09T02:08:30.130502Z","updated_at":"2026-11-02T15:46:17.892347Z"}]}}
