WordPress Security Plugin Bypasses Password Verification in 2FA

The Security Plugin, Firewall & Malware Scanner with Auto Removal WordPress plugin before 2.191 does not verify the account password before accepting an authenticator-app two-factor code at login, allowing anyone who holds a user's current authenticator code to log in as that user, including an administrator, without the password.

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

CVE-2026-114443 represents a critical authentication bypass in the Security Plugin, Firewall & Malware Scanner with Auto Removal for WordPress. The vulnerability allows attackers to gain unauthorized access to any user account—including administrative accounts—by simply possessing a valid authenticator code, completely circumventing password requirements. This flaw affects WordPress installations using versions prior to 2.191 of this widely-deployed security plugin, creating a dangerous paradox where a tool meant to protect sites becomes a vector for compromise. The threat is particularly severe because authenticator codes are time-sensitive but can be intercepted, social engineered, or obtained through various reconnaissance methods, making this a practical attack path for threat actors targeting WordPress administrators.

Casky's 283 mapped skills detect the attack patterns underlying this vulnerability by analyzing authentication workflows against MITRE techniques TA0004 (Reconnaissance) and TA0006 (Credential Access). When practitioners enable extended reasoning analysis, Claude identifies suspicious patterns such as successful 2FA completions without corresponding password authentication events, anomalous login sequences where multi-factor challenges succeed without initial credential validation, and deviations from standard OAuth/TOTP verification flows. Practitioners would observe findings highlighting missing password verification checkpoints in authentication logs, detection of authenticator code replay scenarios, and behavioral anomalies consistent with CWE-287 (Improper Authentication). The platform's skill correlation reveals how attackers exploit this gap through credential stuffing followed by 2FA bypass attempts, enabling rapid lateral movement to administrative accounts.
