WordPress HivePress Plugin Stored XSS via Custom Attributes

The HivePress – Business Directory, Listings & Classified Ads Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '<custom user attribute slug> (e.g. hp_custom_link)' parameter in all versions up to, and including, 1.7.32 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that an administrator has configured a custom user attribute with a display_format template placing the %value% token inside an href, src, or style attribute context, which is a documented and expected use of the plugin's attribute display feature.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched 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 HivePress Business Directory plugin for WordPress contains a stored cross-site scripting (XSS) vulnerability in custom user attribute parameters that allows unauthenticated attackers to inject malicious JavaScript code. With a CVSS score of 7.2, this vulnerability affects all versions up to 1.7.32 and persists in the database, meaning any user visiting an affected page will execute the attacker's script. This is particularly dangerous for WordPress sites hosting classified ads or business directories, as attackers can steal session tokens, harvest credentials, deface content, or redirect users to malicious sites. Organizations running HivePress installations face significant risk if they haven't patched to version 1.7.33 or later, as the vulnerability requires no authentication to exploit.

Casky's 323 matching skills leverage Claude's extended reasoning to identify the attack patterns underlying this vulnerability across MITRE ATT&CK techniques TA0001 (Initial Access) and TA0043 (Reconnaissance). Practitioners would observe detection findings correlating CWE-79 injection patterns with techniques like T1190 (Exploit Public-Facing Application) and T1598 (Phishing) when attackers craft payloads targeting the hp_custom_link parameter. Casky's skill mapping would highlight insufficient input sanitization and output escaping as the root cause, helping teams understand why the vulnerability exists and what code-level defenses (input validation, output encoding, Content Security Policy) prevent exploitation. The platform enables practitioners to trace how stored XSS flows from parameter injection through database persistence to DOM execution, making it easier to identify similar weaknesses in custom WordPress plugins before they become exploitable.
