WordPress Plugin Privilege Escalation via Missing Authorization Checks

The InfusedWoo Pro plugin for WordPress is vulnerable to privilege escalation via missing authorization in all versions up to, and including, 5.1.2. This is due to missing nonce verification and capability checks in the iwar_save_recipe() AJAX handler. This makes it possible for unauthenticated attackers to create a malicious automation recipe that pairs an HTTP post trigger with an auto-login action, allowing any unauthenticated visitor to visit a crafted URL and receive authentication cookies for any targeted user account (e.g., administrator), achieving complete authentication bypass and privilege escalation.

Casky was already ahead

This CVE exploits attack patterns that Casky's 261matched 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 InfusedWoo Pro plugin for WordPress contains a critical privilege escalation vulnerability (CVSS 9.8) in its AJAX handler that fails to verify nonces and validate user capabilities. This flaw allows unauthenticated attackers to create malicious automation recipes that chain an HTTP post trigger with an auto-login action, enabling any visitor to obtain valid authentication cookies by accessing a specially crafted URL. With 261 matching security skills in Casky's framework, this vulnerability represents a severe risk to WordPress sites using affected versions up to 5.1.2, as it completely bypasses authentication mechanisms and grants unauthorized access to authenticated user sessions.

Casky's skill detection would identify this attack pattern by mapping to MITRE ATT&CK techniques TA0004 (Privilege Escalation) and TA0006 (Credential Access). Practitioners would observe findings highlighting missing authorization checks in AJAX handlers (CWE-862), the absence of nonce verification patterns, and suspicious automation recipe creation without proper capability validation. The detection would surface the attack chain of unauthenticated POST requests triggering auto-login actions, flagging the establishment of unauthorized authentication tokens. Extended reasoning across Casky's 754 mapped skills would help teams understand how these missing security controls create a direct path from visitor to authenticated user, enabling defenders to prioritize patching and implement compensating controls like Web Application Firewalls to block exploitation attempts.
