CVE-2026-82973

CriticalCVSS 9.4
Published: Updated: Translated: NVD NIST

Summary

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.

Risk Assessment

An attacker can inject IMAP commands into a mailbox session, potentially leading to unauthorized access to messages or mailbox modification. The risk occurs when bearer-token authentication is not enabled.

Recommendation

Update psyb0t/docker-mailbox to version 0.4.13 or later. Until patched, enable bearer-token authentication and restrict network access to the service.
