Name of the Vulnerable Software and Affected Versions Link Library plugin for WordPress versions up to, and including, 7.6.11

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'link-library' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 7.6.11, consider disabling the 'link-library' shortcode until a patch is available to prevent exploitation. Restrict access to pages that use this shortcode to minimize the risk of arbitrary web script injection. Avoid using user-supplied attributes in the 'link-library' shortcode until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
