AI-suggested
Users should monitor vendor advisories for updates. Until a fix is available, restrict access to the plugin's administrative functions and ensure that the PEAR Archive_Tar library is not unnecessarily installed or accessible. Administrators should be cautious when using the plugin's Rename control on attachments, especially if suspicious comments or payloads are present.
Description
The Optimole WordPress plugin up to version 4.2.19 contains a vulnerability that allows unauthenticated attackers to delete arbitrary files on the server due to insufficient file path validation. Exploitation requires the presence of PEAR's Archive_Tar library and an administrator to perform a rename action on an attachment after the attacker stages a malicious payload in a comment. This can lead to remote code execution if critical files like wp-config.php are deleted.
