CVE-2024-11447

Vulnerability

Overview

The Community by PeepSo plugin for WordPress is vulnerable to Reflected Cross-Site Scripting (XSS) in all versions up to and including 7.0.3.0. The flaw resides in the 'filter' parameter, which lacks sufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts into pages that execute if a user performs an action such as clicking a crafted link [1].

Exploitation and

Attack Surface

Exploitation requires no authentication; an attacker can craft a malicious URL containing the XSS payload in the 'filter' parameter. The attack is reflected, meaning the payload is executed in the context of the victim's browser when they visit the manipulated link. Successful exploitation depends on social engineering to trick a user into clicking the link, such as via phishing or embedding the link in a forum post.

Impact

If exploited, an attacker can execute arbitrary JavaScript in the victim's browser, potentially leading to session hijacking, defacement, or redirection to malicious sites. The CVSS v3 base score of 6.1 (Medium) reflects the need for user interaction and the limited scope of impact typical of reflected XSS.

Mitigation

The vendor released version 7.0.4.0, which addresses this vulnerability along with other security fixes, including a script injection flaw in the search function [1]. Users are strongly advised to update to the latest version to mitigate the risk.
