Webauthn Provider For Two Factor
Monthly
Two-factor authentication bypass in the WebAuthn Provider for Two Factor WordPress plugin (all versions before 2.5.6) lets an attacker who already possesses a valid user's password defeat the WebAuthn second factor by submitting a malformed authentication response that the plugin fails to validate. This neutralizes the plugin's core protection, effectively reducing account security back to single-factor (password-only). Publicly available exploit code exists (reported by WPScan); there is no public exploit identified as being used in active attacks and the issue is not listed in CISA KEV.
