Name of the Vulnerable Software and Affected Versions The Beautiful Cookie Consent Banner for WordPress versions up to, and including, 2.10.1

Description The issue is related to Stored Cross-Site Scripting via the nsc bar content href 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, 2.10.1, update to version 2.10.2 to fully resolve the issue. As a temporary workaround for versions up to 2.10.1, consider restricting access to the nsc bar content href parameter to minimize the risk of exploitation.
