{"schema":"threatline.record/2","record":{"id":"CVE-2026-85749","aliases":["GHSA-w7v5-7g6w-87r4"],"summary":"MailWatch: IDOR lets any authenticated user release or delete another tenant's quarantined mail","details":"MailWatch for MailScanner is a web-based front-end to MailScanner. 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.","categories":["Unclassified"],"product":"MailWatch","vendor":"mailwatch","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-85749","source_modified_at":"2026-10-28T22:37:38.513Z","fetched_at":"2026-10-29T00:48:09.584895Z","product":"MailWatch","vendor":"mailwatch","versions":[{"version":"< 1.2.27","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T22:37:38.513Z","modified_at":"2026-10-28T22:37:38.513Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-85749","fetched_at":"2026-10-29T00:48:09.584895Z","source_modified_at":"2026-10-28T22:37:38.513Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/mailwatch/MailWatch/security/advisories/GHSA-w7v5-7g6w-87r4","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/mailwatch/MailWatch/commit/bc04f25eb0cec028cbd4ded9c049cfc6f663a15f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/mailwatch/MailWatch/releases/tag/v1.2.27","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T22:37:38.513Z","content_hash":"55da9aa80f3867f314e7b73a41a79b376bb86ddf76c6cf3c134c71d1de48cdac"}}
