WordPress OTP Plugin Skips Authentication Verification

The Happy Coders OTP Login for WooCommerce WordPress plugin before 2.8 does not verify that a one-time password was actually validated before authenticating a user based on a supplied identifier, allowing unauthenticated attackers to log in as any existing user, including administrators, as well as to create new accounts.

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 Happy Coders OTP Login for WooCommerce plugin contains a critical authentication bypass flaw that allows attackers to log in as any user without providing valid credentials. By exploiting insufficient OTP validation logic, unauthenticated attackers can assume administrator accounts or create new privileged accounts entirely. This affects all WooCommerce stores using the vulnerable plugin versions before 2.8, putting customer data, payment information, and business operations at severe risk of compromise. The CVSS 9.8 rating reflects the ease of exploitation and complete loss of authentication integrity.

Casky's 283 matching skills detect the attack patterns underlying this vulnerability by analyzing MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky's Claude-powered extended reasoning would identify suspicious authentication flows where OTP validation steps are bypassed or skipped in request sequences. The platform would flag indicators such as successful login events lacking corresponding OTP verification logs, user creation without proper authentication challenges, and privilege escalation to admin roles through unauthenticated endpoints. By mapping these behavioral patterns against the 754 security skills framework, security teams gain visibility into both the technical exploitation mechanisms and the post-authentication lateral movement that typically follows such breaches.
