CVE-2026-114720 at MITRE

Description

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an IMAP command injection vulnerability. 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.
