**Name of the Vulnerable Software and Affected Versions**
User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress versions prior to 20260114
**Description**
The software is susceptible to an authorization issue. This is due to the `usp get submitted category()` function improperly handling user-supplied category IDs received in the POST request body. Specifically, the function does not validate these IDs against the allowed categories configured by the administrator and stored in `usp options['categories']`. This allows unauthenticated attackers to assign submitted posts to any category, including restricted ones, by manipulating the `user-submitted-category[]` values in a direct POST request, effectively bypassing frontend category restrictions.
**Recommendations**
Update to a version later than 20260113.
