Name of the Vulnerable Software and Affected Versions
Open WebUI versions prior to 0.10.0
Description
The '/api/v1/auths/signin' endpoint performs user lookups by email and only executes bcrypt password verification if a matching credential is found. This creates a timing difference where requests for registered accounts take measurably longer than requests for non-existent emails, enabling unauthenticated account enumeration.
Recommendations
Update to version 0.10.0.
