WordPress · User Submitted Posts · CVE-2023-4308
**Name of the Vulnerable Software and Affected Versions**
User Submitted Posts plugin for WordPress versions up to, and including, 20230809
**Description**
The issue is related to Stored Cross-Site Scripting via the `user-submitted-content` parameter due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
**Recommendations**
For versions up to, and including, 20230809, consider disabling the `user-submitted-content` parameter until a patch is available to prevent exploitation. Restrict access to areas where user-submitted content is displayed to minimize the risk of arbitrary web script execution. Update to a version that includes proper input sanitization and output escaping for the `user-submitted-content` parameter to fully resolve the issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
