Prior to 1.2.27, any authenticated MailWatch user, including the U/user, D/domain-admin, and H/host roles, can release to inbox or permanently delete the quarantined mail of any other user or domain by supplying an arbitrary message `id` to `mailscanner/quarantine_action.php`. The action path calls `quarantine_list_items()` in `mailscanner/functions.php`, which selects from `maillog` by the supplied identifier without the per-role `global_filter` applied by listing and read views. The action requires a valid session and CSRF token, but the caller can submit a token from the caller's own session; ownership of the requested message is never checked. Message identifiers are enumerable, allowing a low-privilege user to invoke `quarantine_release()` or `quarantine_delete()` for other users' or domains' quarantined messages, force-delivering mail held by the quarantine or permanently deleting it. This issue is fixed in version 1.2.27.","state":0,"publishedAt":"2026-10-28T22:37:38.513+00:00","modifiedAt":"2026-10-28T22:37:38.513+00:00","affected":[{"ecosystem":"Vendor product","name":"MailWatch","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"mailwatch\",\n                    \"product\": \"MailWatch\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.2.27\",\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:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/mailwatch/MailWatch/security/advisories/GHSA-w7v5-7g6w-87r4","https://github.com/mailwatch/MailWatch/commit/bc04f25eb0cec028cbd4ded9c049cfc6f663a15f","https://github.com/mailwatch/MailWatch/releases/tag/v1.2.27"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-85749","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-85749","identifiers":["CVE-2026-85749"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
