PYSEC-2026-3620 Thumbor has HMAC validation bypass via multiple .replace() calls when removing URL signature

HMAC validation bypass via multiple .replace calls when removing URL signature Summary Thumbor’s HMAC validation can be bypassed due to the use of Python’s .replace when removing the signature from the URL before validation. Since .replace removes all occurrences of the substring, an attacker can...

PYSEC-2026-3594 Open WebUI: Account enumeration via observable login timing discrepancy

Summary The /api/v1/auths/signin endpoint leaked whether an email address belonged to a registered account through a response-time side channel. Password verification ran bcrypt only when the email was found in the database; for a non-existent email the request returned early without hashing. The...
