Description
PLANKA 2.2.0 through 2.2.1 fails to limit incorrect TOTP codes submitted to POST /api/access-tokens/verify-totp, allowing attackers to brute force two-factor authentication codes. Attackers who know a user's password can reuse the ten-minute pending token to guess six-digit codes until one succeeds, obtaining a full access token.
