AI-suggested
A fixed version 0.4.13 or later should be applied to remediate this vulnerability. If bearer-token authentication is configured, the attack vector is mitigated. Until patched, configuring bearer-token authentication may reduce exposure.
Description
Improper neutralization of CRLF sequences in IMAP command construction in psyb0t/docker-mailbox before 0.4.13 allows a remote unauthenticated attacker, when bearer-token authentication is not configured, to inject additional IMAP commands into an authenticated upstream mailbox connection via crafted folder, UID, or search values.
