Exploitation Probability (EPSS)

20th percentile - higher than 20% of all known CVEs

Summary

The Total Upkeep WordPress plugin before 1.17.3 does not adequately protect the secret that authorizes its backup-restore functionality and exposes it to unauthenticated users, allowing them to disclose sensitive backup information and to force a full site restore that overwrites the live site's files and database. This is an incomplete fix of CVE-2020-36848, as the protection added at the time never took effect on distributed copies of the plugin.

Risk Assessment

Risk of complete takeover of the WordPress site, including overwriting files and database, potentially leading to data loss and site integrity compromise.

Recommendation

Immediately update the Total Upkeep plugin to version 1.17.3 or later and restrict restore functionality access to trusted administrators only.
