CVE-2024-52465: LGPD Framework Reflected XSS Vulnerability

CVE-2024-52465 Overview

CVE-2024-52465 is a reflected cross-site scripting (XSS) vulnerability in the Data443 Risk Mitigation LGPD Framework plugin for WordPress. The flaw stems from improper neutralization of user-supplied input during web page generation, classified under [CWE-79]. The vulnerability affects LGPD Framework versions up to and including 2.0.2. Attackers can craft malicious links that, when clicked by an authenticated or unauthenticated victim, execute arbitrary JavaScript in the victim's browser under the site's origin. The scope-changed impact allows attackers to affect resources beyond the vulnerable component.

Critical Impact
Successful exploitation enables session hijacking, credential theft, and unauthorized actions performed in the context of the victim's WordPress session.

Affected Products

Data443 Risk Mitigation LGPD Framework plugin for WordPress
LGPD Framework versions from n/a through 2.0.2
WordPress sites using the lgpd-framework plugin

Technical Details for CVE-2024-52465

Vulnerability Analysis

The LGPD Framework plugin fails to sanitize or encode user-controlled input before reflecting it back into HTTP responses. Attackers embed JavaScript payloads within request parameters that the plugin renders directly into the returned HTML page. When a victim loads the crafted URL, the browser parses and executes the injected script within the trust context of the WordPress site.

The reflected nature of the flaw requires user interaction, typically through a phishing link or attacker-controlled referrer. Because the vulnerability crosses trust boundaries within the browser, injected scripts can access cookies not flagged as HttpOnly, manipulate DOM content, and issue authenticated requests on behalf of the victim.

Root Cause

The plugin does not apply output encoding functions such as esc_html(), esc_attr(), or wp_kses() to user-supplied parameters before echoing them to the response body. This omission allows raw HTML and JavaScript to reach the rendered page. Refer to the Patchstack WordPress Vulnerability advisory for parameter-level detail.

Attack Vector

An attacker delivers a crafted URL containing a JavaScript payload in a vulnerable query parameter handled by the LGPD Framework plugin. The victim clicks the link while browsing the target WordPress site, and the plugin reflects the payload into the HTML response. The browser then executes the script under the site's origin, granting the attacker access to session tokens, form data, and any privileged actions available to the victim.

Exploitation code is not required to demonstrate the flaw; a single crafted URL with an embedded <script> tag or event handler in a reflected parameter is sufficient. See the Patchstack advisory for further technical context.

Detection Methods for CVE-2024-52465

Indicators of Compromise

HTTP request logs containing <script>, javascript:, onerror=, or onload= substrings in query parameters targeting lgpd-framework endpoints
Referrer headers pointing to unknown external domains that link into the plugin's URLs
Unexpected outbound requests from user browsers to attacker-controlled domains shortly after visiting the site

Detection Strategies

Inspect web server access logs for URL-encoded script fragments (%3Cscript%3E, %3Cimg) in requests handled by the LGPD Framework plugin
Deploy a web application firewall (WAF) with signatures for reflected XSS patterns targeting WordPress plugin parameters
Enable browser Content Security Policy (CSP) violation reporting to identify blocked inline script execution attempts

Monitoring Recommendations

Alert on anomalous parameter values submitted to plugin endpoints, particularly those containing HTML tags or JavaScript keywords
Correlate WordPress authentication events with suspicious referrers or short-lived sessions that follow XSS-shaped URLs
Track outbound HTTP requests from administrator browsers to unexpected domains during active WordPress sessions

How to Mitigate CVE-2024-52465

Immediate Actions Required

Upgrade the LGPD Framework plugin beyond version 2.0.2 once a patched release is available from Data443
Disable or remove the lgpd-framework plugin on any WordPress site that cannot be patched immediately
Force password resets and invalidate active sessions for administrator accounts that may have been targeted

Patch Information

Data443 has not published a fixed version referenced in the NVD entry at the time of writing. Monitor the Patchstack advisory and the vendor's plugin repository for update availability. Apply the vendor patch as soon as it is released and verify the installed version through the WordPress plugin management interface.

Workarounds

Deploy a WAF rule that blocks requests containing script tags or event handler attributes in parameters bound for the plugin
Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
Restrict access to plugin URLs through IP allowlists or authentication where operationally feasible

bash
