Administrative access via MFA lockout enforcement gap
Published Sep 29, 2025 · Updated Sep 29, 2025
Authentication bypass in Obsidian Scheduler 5.0.0 through 6.3.0 allows remote authenticated users to create privileged accounts via REST. The REST API accepts Basic Authentication for accounts locked by the MFA enrollment policy instead of applying the web interface's account-state check. Exploitation requires valid administrative credentials, including unchanged default credentials, and grants administrative API access that can execute enabled built-in jobs.
