Name of the Vulnerable Software and Affected Versions The Link Library plugin for WordPress versions up to, and including, 7.7.3

Description The issue is related to Stored Cross-Site Scripting via the Link Additional Parameters due to insufficient input sanitization and output escaping. 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, 7.7.3, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting Contributor-level access and above to minimize the risk of exploitation.
