CVE-2023-1780

Name of the Vulnerable Software and Affected Versions Companion Sitemap Generator WordPress plugin versions prior to 4.5.3

Description The issue is related to the lack of protection of the web page structure, allowing for potential exploitation. Specifically, the plugin does not sanitize and escape certain parameters before outputting them back in pages, leading to Reflected Cross-Site Scripting. This could be used against high-privilege users, such as administrators.

Recommendations For versions prior to 4.5.3, update to version 4.5.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's functionality until a patch is applied. Avoid using the vulnerable parameters in the affected pages until the issue is resolved.
