9.4 CRITICALPublished 2026-09-29 · Updated 2026-09-29
AI risk analysis
- Summary
- The flaw involves improper handling of CRLF sequences in IMAP command construction, allowing remote unauthenticated attackers to inject additional commands, potentially leading to unauthorized access or data manipulation.
- Exploitability
- Exploitation is relatively straightforward when bearer-token authentication is not configured, requiring crafted folder, UID, or search values.
- Blast radius
- If exploited, the impact could be significant, as it allows remote attackers to inject commands into an authenticated connection, potentially leading to data leakage or manipulation.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to psyb0t/docker-mailbox 0.4.13 or later.
