A remote authenticated attacker can exploit this via CRLF sequences injected into the _flag parameter of the mail/mark action to execute arbitrary IMAP commands. Upstream fixed this in the commit “Fix IMAP command injection via CRLF in `_flag` parameter of mail/mark action”, which rejects flags containing control, whitespace and IMAP-special characters.","published":"2026-10-22T02:17:00.000Z","lastModified":"2026-10-26T17:17:16.000Z","status":"Undergoing Analysis","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N"},"cwe":["CWE-93"],"affected":[],"epss":{"score":0.00806,"percentile":0.56537,"date":"2026-10-26","history":[{"date":"2026-10-22","score":0.00805,"percentile":0.56331}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.81%).
