CVE-2023-6561

Name of the Vulnerable Software and Affected Versions Featured Image from URL (FIFU) plugin for WordPress versions up to, and including, 4.5.3

Description The issue is related to Stored Cross-Site Scripting via the featured image alt text 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, 4.5.3, update to a version higher than 4.5.3 to resolve the issue. As a temporary workaround, consider restricting access to the featured image alt text input field to minimize the risk of exploitation.
