Stored XSS in WordPress Form Builder Map Fields

The Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Mark on Map Longitude/Latitude Fields in all versions up to, and including, 1.15.47 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 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 Form Maker by 10Web plugin contains a Stored Cross-Site Scripting (CWE-79) vulnerability in its Map longitude and latitude input fields that fails to properly sanitize user input or escape output. This allows unauthenticated attackers to inject malicious JavaScript that persists in the database and executes whenever any user views the affected form or page. The vulnerability poses a significant risk to WordPress sites using this popular form builder plugin, potentially compromising visitor sessions, stealing credentials, or spreading malware to thousands of site visitors without requiring authentication. With 323 matching skills in Casky's framework and a CVSS score of 7.2, this represents a high-severity threat affecting website integrity and user security.

Casky's AI-powered detection leverages 754 security skills mapped to MITRE ATT&CK to identify attack patterns associated with TA0001 (Initial Access) and TA0043 (Reconnaissance). Practitioners using Casky would observe findings highlighting unsafe input handling in form field processors, detection of script injection attempts in coordinate parameters, and patterns consistent with stored payload delivery mechanisms. The platform's extended reasoning capabilities would correlate insufficient input sanitization at the persistence layer with output encoding gaps, flagging the attack chain from unauthenticated input submission through stored script execution. Defenders would receive specific alerts on form submission endpoints lacking input validation, database storage of unescaped user content, and rendered page elements that execute injected scripts—enabling rapid remediation before exploitation.
