Summary
The Forminator Forms plugin for WordPress is vulnerable to limited file deletion in all versions up to and including 1.55.0.2. The plugin accepts arbitrary upload field metadata from POST requests in draft submissions without proper validation (CWE-73), and later uses that metadata to delete files when a subsequent draft references the poisoned draft through the previous_draft_id parameter. An unauthenticated attacker can delete arbitrary non-PHP files within the wp-content/uploads/ directory.

Description from the CNA
The Forminator Forms plugin for WordPress is vulnerable to Limited File Deletion in all versions up to, and including, 1.55.0.2. This is due to the plugin accepting arbitrary upload field metadata from POST requests in draft submissions without proper validation, which is then used to delete files when a subsequent draft references the poisoned draft via the previous_draft_id parameter. This makes it possible for unauthenticated attackers to delete arbitrary non-PHP files within the wp-content/uploads/ directory.
