Short explanation
The wp-downloadmanager plugin before version 1.69 allows admin users to upload arbitrary files without validation, leading to remote code execution. No file-type or path traversal checks exist in version 1.68.11. The vulnerability was confirmed by the plugin's own changelog.
This vulnerability allows attackers to execute arbitrary code on affected systems via a legitimate file upload, posing a high risk to WordPress installations using outdated versions of the plugin.
What should be done?
- Upgrade to version 1.69 or later as per official vendor advisories.
- Do not use the plugin if version 1.69 or later is not available.
