WordPress · Formula Theme · CVE-2024-5638
**Name of the Vulnerable Software and Affected Versions**
Formula theme for WordPress versions up to, and including, 0.5.1
**Description**
The issue is related to Reflected Cross-Site Scripting via the `id` parameter in the "ti customizer notify dismiss recommended plugins" AJAX action. This is due to insufficient input sanitization and output escaping, making it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
**Recommendations**
For versions up to, and including, 0.5.1, consider disabling the "ti customizer notify dismiss recommended plugins" AJAX action until a patch is available. Restrict access to the `id` parameter in the affected AJAX endpoint to minimize the risk of exploitation. Avoid using the `id` parameter in the "ti customizer notify dismiss recommended plugins" AJAX action until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
