What the vulnerability does
The Color Palette plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘hex’ parameter in all versions up to, and including, 4.3.2 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
Color Palette versions 4.3.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts affecting other users. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Site administrators should update to a version newer than 4.3.2 to remediate this issue.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors; potential for credential theft or site defacement.
Conditions required to exploit
Attacker must have a low-privilege user account on the site; no user interaction required.
