CVE-2025-4406: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in tomdever wpForo Forum
The wpForo Forum plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 2.4.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
AI Analysis
Technical Summary
CVE-2025-4406 is a stored cross-site scripting vulnerability in the wpForo Forum WordPress plugin, affecting all versions up to 2.4.5. The issue stems from improper neutralization of input during web page generation, specifically via SVG file uploads. Authenticated attackers with at least Subscriber privileges can upload crafted SVG files containing malicious scripts. These scripts execute in the context of users who view the SVG, enabling potential unauthorized actions or data exposure. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 5.4, indicating medium severity. No patch or official remediation guidance is currently available.
Potential Impact
Successful exploitation allows authenticated users with Subscriber-level access or higher to inject and execute arbitrary scripts in the context of other users viewing the SVG files. This can lead to limited confidentiality and integrity impacts, such as session hijacking or unauthorized actions performed on behalf of users. There is no reported impact on availability. No known exploits are currently observed in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict SVG file uploads to trusted users only or disable SVG uploads if possible. Monitor plugin updates from the vendor for a security patch addressing this vulnerability.
