CVE-2024-2260Public exploitNetwork attack vector

Continued account access via reusable logged-out JWT

Published Apr 16, 2024 · Updated Aug 1, 2024

Session fixation in ZenML before 0.56.2 allows remote attackers to retain account access by replaying a victim's logged-out JWT. The logout flow does not invalidate the signed JWT, so later requests bearing the token remain authenticated. Exploitation requires acquisition of a victim's token and user interaction with logout; successful reuse permits access and actions within that account.
