What to do

Update, patch or deactivate.

This archive could not verify a fixed version from the official author release notes reviewed on 2026-10-13. Disable the affected feature or component where practical until remediation for the deployed configuration is established. Disable that remote-fetch mode until fixed; restrict destinations, resolve and reject internal addresses and validate each redirect before making requests. Official author release notes: https://wordpress.org/plugins/wp-asset-clean-up/.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Asset CleanUp: Page Speed Booster plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.4.0.5 via the 'page_url' parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. This vulnerability is only reachable when the plugin's dom_get_type setting has been configured to 'wp_remote_post' by an administrator.
