What the vulnerability does
01Description
The Featured Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image metadata in all versions up to, and including, 2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Explanation of Vulnerability in Simple Terms
02Summary
Featured Image versions 2.1 and earlier contain a cross-site scripting vulnerability that allows high-privilege users to inject malicious scripts affecting other users or the site. The vulnerability requires high attack complexity and high privileges to exploit. Scope is changed, meaning the impact extends beyond the vulnerable component itself.
