What the vulnerability does
01Description
The RandomQuotr plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.0.4 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
RandomQuotr versions 1.0.4 and earlier contain a cross-site scripting (XSS) vulnerability that allows high-privilege users to inject malicious scripts affecting other users or the site. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. An attacker with administrative or equivalent access can craft payloads that execute in other users' browsers.
