WordPress 2FA Plugin Fails to Validate One-Time Passwords

The miniOrange 2FA WordPress plugin before 6.2.6 does not validate the submitted one-time password against the targeted user's stored secret, instead verifying it against an attacker-supplied value, allowing an unauthenticated attacker who knows a victim's password to bypass two-factor authentication and gain access to the victim's account, including administrators.

Casky was already ahead

This CVE exploits attack patterns that Casky's 283matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The miniOrange 2FA WordPress plugin before version 6.2.6 contains a critical authentication bypass vulnerability where submitted one-time passwords (OTPs) are validated against attacker-controlled values rather than the legitimate user's stored secret. This allows an unauthenticated attacker who possesses a victim's password to completely bypass two-factor authentication protections and gain unauthorized account access. The vulnerability is particularly severe because it affects administrative accounts, making it a direct pathway to full WordPress installation compromise. Any organization using this plugin version is at immediate risk of account takeover, data theft, and malware deployment.

Casky's 283 matched security skills leverage Claude's extended reasoning to detect the attack patterns associated with TA0004 (Privilege Escalation) and TA0006 (Credential Access) techniques. Practitioners using Casky would identify suspicious authentication flows where OTP validation logic deviates from cryptographic best practices—specifically, detecting when verification occurs against user-supplied input rather than server-side secrets. The platform would surface findings related to insecure authentication mechanisms (CWE-287), highlighting failed 2FA implementations that inadvertently trust client-side or attacker-controlled validation parameters. Teams would see flagged indicators including: successful authentications despite incorrect OTP submission, authentication logs showing password-only compromise followed by account access, and plugin configuration allowing external OTP values. These skill matches enable defenders to rapidly identify compromised instances and implement compensating controls before exploitation occurs.
