CVE-2025-54573Network attack vector

Verified-user access via unchecked Basic authentication

Published Jul 30, 2025 · Updated Jul 30, 2025

Authentication bypass in CVAT 1.1.0 through 2.41.0 allows remote authenticated users to act as verified users via Basic HTTP Authentication. The BasicAuthentication backend accepts valid credentials without checking the EmailAddress verification state when mandatory verification is configured. An attacker must register an account and know its credentials; fake-email and bot accounts can then consume service resources as verified users.
