**Name of the Vulnerable Software and Affected Versions** Shortcodes and extra features for Phlox theme plugin for WordPress versions up to, and including, 2.15.2 **Description** The issue concerns PHP Object Injection via deserialization of untrusted input from the vulnerable `id` parameter in the `auxin template control importer` function. This allows authenticated attackers to inject a PHP Object by uploading a separate PHAR payload as an image file, potentially enabling them to delete arbitrary files, retrieve sensitive data, or execute code if a POP chain is present via an additional plugin or theme. **Recommendations** For versions up to, and including, 2.15.2, update to a version that fixes the PHP Object Injection vulnerability to prevent exploitation. As a temporary workaround, consider restricting access to the `auxin template control importer` function and the `id` parameter to minimize the risk of exploitation. Avoid using the `id` parameter in the affected function until the issue is resolved.
