- CVE-2026-18052, 22 Aug 2026
- The ManageWP Worker WordPress plugin before 4.9.37 does not bind the account being logged in to the signature which authorises the login, nor prevent an already used login link from being replayed, allowing attackers who obtain such a link to gain a session as any user on the site, including an administrator. CVE record
- CVE-2026-3718, 14 May 2026
- The ManageWP Worker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'MWP-Key-Name' HTTP request header in all versions up to, and including, 4.9.31. This is due to insufficient input sanitization and output escaping of attacker-controlled header values. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator visits the plugin's connection management page with debug parameters. CVE record
What to do if you run ManageWP Worker
If you run ManageWP Worker, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
