CVE-2024-13874
📋 TL;DR
The Feedify WordPress plugin before version 2.4.6 contains a reflected cross-site scripting (XSS) vulnerability where unsanitized user input is reflected back in page output. This allows attackers to inject malicious scripts that execute in the browser of authenticated users, particularly targeting high-privilege administrators. WordPress sites using vulnerable versions of the Feedify plugin are affected.
💻 Affected Systems

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal administrator session cookies, perform actions as the administrator (including installing malicious plugins/themes, modifying content, or creating backdoors), and potentially compromise the entire WordPress site.
Likely Case
Attackers craft malicious links containing XSS payloads and trick administrators into clicking them, leading to session hijacking or limited administrative actions.
If Mitigated
With proper input validation and output escaping, the malicious scripts would be neutralized, preventing execution even if the vulnerable parameter is accessed.
🎯 Exploit Status
The vulnerability is reflected XSS, which typically requires user interaction (clicking a malicious link). Exploitation details are publicly available in the WPScan reference.
