What the vulnerability does
The Simple Featured Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘slideshow’ parameter in all versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping. This makes it possible for 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.
Explanation of Vulnerability in Simple Terms
Simple Featured Image versions 1.3.1 and earlier contain a cross-site scripting vulnerability. An attacker with low-level site access can inject malicious scripts that execute in other users' browsers, potentially stealing session tokens or performing actions on their behalf. The vulnerability affects the entire site due to scope change.
What an attacker can do
Inject malicious scripts that run in other users' browsers and steal their session data or perform actions as them.
Potential impact on your site
Any logged-in user, including admins, can be compromised if an attacker with contributor or editor access injects malicious code.
Conditions required to exploit
Attacker needs a low-privilege account on the site; no user interaction required from the victim.
