WordPress Wurdey Plugin Missing Request Signature Verification

The Wurdey WordPress plugin through 1.0.0 does not verify a request signature before logging a user in, allowing unauthenticated attackers to authenticate as an administrator knowing only the administrator's username.

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 Wurdey WordPress plugin through version 1.0.0 contains a critical authentication bypass vulnerability (CVE-2026-110955, CVSS 9.8) stemming from missing request signature verification during login operations. This flaw allows unauthenticated attackers to assume administrator privileges by simply knowing the target admin's username—no password required. Any WordPress site running the vulnerable plugin becomes immediately exposed to account takeover, with attackers gaining full administrative control to modify content, install malicious code, create backdoors, and exfiltrate sensitive data. This affects all organizations using WordPress with this plugin installed, particularly those with public-facing sites where administrator usernames are discoverable through common enumeration techniques.

Casky's 283 mapped security skills detect the attack patterns underlying this vulnerability by correlating MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access) through Claude's extended reasoning capabilities. Practitioners using Casky would identify indicators including: anomalous authentication requests lacking proper cryptographic validation, successful administrative logins from unexpected sources without corresponding credential submission events, and malformed or missing signature parameters in authentication payloads. The platform flags CWE-287 (Improper Authentication) violations by detecting login state changes that bypass normal authentication workflows, allowing security teams to pinpoint plugin-specific request handlers that fail to implement signature verification before granting elevated privileges—enabling rapid patching and remediation before exploitation occurs.
