CVE-2024-2840: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in webbistro Enhanced Media Library
The Enhanced Media Library plugin for WordPress is vulnerable to Stored Cross-Site Scripting via media upload functionality in all versions up to, and including, 2.8.9 due to the plugin allowing 'dfxp' files to be uploaded. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2024-2840 is a stored cross-site scripting vulnerability in the Enhanced Media Library WordPress plugin (versions up to 2.8.9). It arises because the plugin allows uploading 'dfxp' files without proper input neutralization, enabling authenticated users with author-level access or higher to inject arbitrary web scripts. These scripts execute when any user accesses the injected page, potentially compromising user sessions or data. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity. No patch or official fix information is currently available.
Potential Impact
Successful exploitation allows authenticated users with author-level or higher privileges to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to limited confidentiality and integrity impacts, such as session hijacking or content manipulation. There is no indication of availability impact. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict author-level and higher user permissions to trusted individuals only. Consider disabling or limiting the upload of 'dfxp' files if possible. Monitor vendor communications for updates and apply patches promptly once available.
