What is CVE-2024-8480?

The Sirv plugin for WordPress is susceptible to a vulnerability that permits unauthorized modification of data. This occurs due to a missing capability check in the 'sirv_save_prevented_sizes' function, making all versions up to and including 7.2.7 affected. Authenticated users with Contributor-level permissions and higher can exploit the flaw in the 'sirv_upload_file_by_chunks_callback' function. This function fails to perform adequate file type validation, enabling attackers to upload arbitrary files onto the server of the affected site, thereby potentially leading to remote code execution.

Affected Version(s)

Image Optimizer, Resizer and CDN – Sirv * <= 7.2.7
