CVE-2024-31363 Overview
CVE-2024-31363 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the LifterLMS WordPress plugin. The flaw impacts all versions up to and including 7.5.0. LifterLMS is a learning management system (LMS) plugin used by educators and businesses to deliver online courses through WordPress sites.
The vulnerability is classified under [CWE-352] (Cross-Site Request Forgery). Successful exploitation requires an authenticated user to interact with an attacker-controlled link or page. Once triggered, the attacker can perform actions in the context of the victim, potentially affecting confidentiality, integrity, and availability of the targeted site.
Critical Impact
An attacker can trick an authenticated LifterLMS administrator into executing unintended state-changing requests, leading to high impact on data confidentiality, integrity, and site availability.
Affected Products
- LifterLMS WordPress plugin versions up to and including 7.5.0
- WordPress sites running LifterLMS with administrative sessions active
- Deployments matching CPE cpe:2.3:a:lifterlms:lifterlms:*:*:*:*:*:wordpress:*:*

Technical Details for CVE-2024-31363
Vulnerability Analysis
The vulnerability stems from missing or insufficient CSRF protections in state-changing endpoints exposed by the LifterLMS plugin. WordPress plugins typically rely on nonce tokens generated via wp_create_nonce() and validated through check_admin_referer() or wp_verify_nonce(). When these checks are absent or improperly enforced, an attacker can craft a request that the victim's browser submits automatically using their authenticated session cookies.
Exploitation requires user interaction, meaning the victim must visit a malicious page or click a crafted link while authenticated to the target WordPress site. Because LifterLMS handles administrative configuration, course content, and user management, a successful CSRF action can modify plugin settings or course data without the victim's knowledge.
The scope is unchanged, but impact on confidentiality, integrity, and availability is high. This indicates the abused endpoints can alter sensitive plugin state or expose data that the authenticated user is authorized to access.
Root Cause
The root cause is the absence of proper anti-CSRF token validation on sensitive plugin actions. Without verifying nonce values tied to the user session, the plugin accepts forged requests originating from third-party origins as legitimate.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a page containing a hidden form or <img> tag that targets a vulnerable LifterLMS endpoint. When the authenticated victim visits the attacker's page, the browser automatically submits the request with valid session cookies, and the server processes it as authorized.
The vulnerability mechanism is described in the Patchstack LifterLMS CSRF Vulnerability advisory. No public proof-of-concept code has been released.
Detection Methods for CVE-2024-31363
Indicators of Compromise
- Unexpected configuration changes within the LifterLMS plugin settings, including course, enrollment, or user role modifications not initiated by administrators.
- HTTP POST or GET requests to LifterLMS admin endpoints with Referer headers pointing to untrusted external domains.
- Administrator account activity originating from sessions immediately after visiting unfamiliar third-party URLs.
Detection Strategies
- Review WordPress access logs for state-changing requests to wp-admin/admin.php and LifterLMS action handlers lacking valid nonce parameters.
- Correlate session activity with browser history or referrer data to identify cross-origin request patterns.
- Enable WordPress audit logging plugins to track plugin setting changes, course edits, and user role modifications.
Monitoring Recommendations
- Monitor web server logs for anomalous request bursts targeting LifterLMS endpoints during administrator sessions.
- Alert on changes to LifterLMS configuration tables in the WordPress database outside of expected administrative workflows.
- Track outbound referrer headers from administrator browser sessions to detect interaction with suspicious external sites.
How to Mitigate CVE-2024-31363
Immediate Actions Required
- Upgrade LifterLMS to a version later than 7.5.0 that includes the CSRF fix referenced in the Patchstack advisory.
- Force re-authentication of all WordPress administrator and instructor accounts after applying the patch.
- Audit recent plugin configuration changes, course content edits, and user role assignments for unauthorized modifications.
Patch Information
The vendor has released a fixed version of the LifterLMS plugin addressing the missing CSRF protections. Refer to the Patchstack LifterLMS CSRF Vulnerability advisory for the corrected version and remediation guidance. Administrators should apply the update through the WordPress plugin management interface or via WP-CLI.
Workarounds
- Restrict access to wp-admin endpoints by IP allowlisting at the web server or web application firewall (WAF) layer.
- Require administrators to use separate browser profiles or sessions for WordPress management to reduce cross-site request exposure.
- Deploy a WAF rule that enforces same-origin Referer and Origin header checks on LifterLMS administrative requests until patching is complete.
# Configuration example: update LifterLMS via WP-CLI
wp plugin update lifterlms
wp plugin get lifterlms --field=version
