WordPress Form Vibes Plugin Stored XSS via Contact Form 7

The Form Vibes – Database Manager for Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Contact Form 7 Form Field in all versions up to, and including, 1.5.2 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.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched 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 Form Vibes – Database Manager for Forms plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability that allows unauthenticated attackers to inject malicious scripts through Contact Form 7 form fields. Because the vulnerability exists in all versions up to 1.5.2 and requires no authentication, any visitor can craft a malicious form submission containing JavaScript code. When legitimate users later access pages containing the injected form data, the malicious script executes in their browsers with their privileges—potentially stealing session tokens, credentials, or sensitive information. This vulnerability poses significant risk to WordPress sites using this plugin, as the attack surface spans all unauthenticated users and the payload persists in the database, affecting every subsequent visitor.

Casky's 322 matched skills use Claude's extended reasoning to map this vulnerability to Resource Development (TA0001) techniques—where attackers gather information about target WordPress installations—and Execution (TA0043) techniques involving script injection. Practitioners using Casky will observe detections across the attack chain: initial reconnaissance of Form Vibes installations, suspicious Contact Form 7 field submissions containing script tags or event handlers, and post-exploitation behavior like credential exfiltration. The platform's skill mapping enables defenders to correlate insufficient input sanitization patterns (CWE-79) with actual MITRE ATT&CK execution, revealing not just that XSS exists, but how adversaries chain it into broader attack workflows targeting WordPress environments at scale.
