Short explanation
Roundcube Webmail versions prior to 1.6.20 and 1.7.5 are vulnerable to IMAP command injection via CRLF sequences in the _uid parameter, allowing an authenticated attacker to execute arbitrary IMAP commands.
Because client‑side email services are widespread, this exploit can grant unauthorized access to email content and accounts.
What should be done?
- Upgrade to Roundcube 1.6.20 or 1.7.5 or later
- Apply patch references (S0)
- Verify deployed version
- Monitor for suspicious IMAP activity
- Enforce strong authentication and session management
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
