Name of the Vulnerable Software and Affected Versions The Image Optimizer, Resizer and CDN – Sirv plugin for WordPress versions up to, and including, 7.3.0

Description The issue is related to insufficient validation on the filename parameter of the sirv upload file by chunks() function, allowing authenticated attackers with Contributor-level access and above to delete arbitrary option values on the WordPress site. This can lead to a denial of service by creating an error on the site and denying service to legitimate users.

Recommendations For versions up to, and including, 7.3.0, update to a version higher than 7.3.0 to resolve the issue. As a temporary workaround, consider restricting access to the sirv upload file by chunks() function until a patch is available. Restrict Contributor-level access and above to minimize the risk of exploitation.
