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.
