CVE-2026-49217

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Mailu is a mail server as a set of Docker images. Prior to version 2024.06.52, a missing authorization check in the Mailu admin REST API allows any unauthenticated attacker to remove any potential IP restriction or update the comment field from any existing user token provided the REST API is enabled. Upgrade to Mailu 2024.06.52 to receive a patch or, as a workaround, turn the REST API off.
