CVE-2024-8964

Name of the Vulnerable Software and Affected Versions: The Image Optimizer, Resizer and CDN – Sirv plugin for WordPress versions up to, and including, 7.2.9

Description: The issue is related to Stored Cross-Site Scripting via SVG File uploads due to insufficient input sanitization and output escaping. This allows authenticated attackers with Author-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.

Recommendations: For versions up to, and including, 7.2.9, update to a version higher than 7.2.9 to resolve the issue. As a temporary workaround, consider restricting access to SVG file uploads for users with Author-level access and above until a patch is available. Restrict access to the vulnerable SVG File uploads feature to minimize the risk of exploitation.
