CVE-2026-56450Network attack vector

Account access via unlimited 2FA code guesses

Published Jun 22, 2026 · Updated Jun 22, 2026

Missing rate limiting in AIL Framework 6.8.0 and earlier allows remote attackers to gain account access via repeated OTP guesses. The verify_2fa route checked each submitted code without recording failed OTP attempts or enforcing a retry limit. The attacker must first reach the 2FA step, such as by completing password authentication, before unlimited guesses can defeat the second factor.
