WordPress Plugin Bypasses Password Authentication via Email

The teddy-bear-customize-addon WordPress plugin through 1.0.5 does not verify a user's password before authenticating them, allowing unauthenticated attackers to log in as any registered user, including administrators, by supplying only that user's email address.

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 teddy-bear-customize-addon WordPress plugin through version 1.0.5 contains a critical authentication bypass vulnerability (CWE-287) that completely removes password verification from the login process. Attackers can authenticate as any registered user—including administrators—by supplying only an email address, with no valid credentials required. This affects all WordPress installations using this plugin, creating an immediate pathway to administrative compromise. The CVSS 9.8 critical rating reflects the severe impact: unauthorized access to sensitive site data, malware injection, user account takeover, and complete site defacement become trivial for unauthenticated attackers.

Casky's 283 mapped security skills, leveraging Claude AI's extended reasoning capabilities, detect the attack patterns underlying this vulnerability across MITRE ATT&CK tactics TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners using Casky would identify suspicious authentication events showing successful logins with email-only submissions, absence of password hash validation in plugin code analysis, and anomalous admin account access from unexpected sources or IPs. The platform's skills would correlate failed legitimate login attempts against successful email-only authentications, flag rapid account enumeration followed by direct access grants, and surface indicators of privilege escalation when standard user emails gain administrative capabilities. Security teams would see detailed findings highlighting the missing authentication control, enabling rapid patching decisions and investigation of potentially compromised accounts prior to plugin update deployment.
