Prior to 1.8.221, while investigating the ThreadPolicy::delete issue reported previously, the same missing mailbox membership check was found in the sibling ThreadPolicy::edit method. A user with the PERM_EDIT_CONVERSATIONS permission who created a message or internal note in Mailbox A can rewrite that thread's body after an administrator removes them from Mailbox A, because the policy checks only authorship and a global permission flag — not current mailbox membership. This vulnerability is fixed in 1.8.221.","published":"2026-05-29T20:16:29.000Z","lastModified":"2026-07-22T06:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-285"],"affected":[],"epss":{"score":0.00155,"percentile":0.04605,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.15%).
