CVE-2024-54413 Overview
CVE-2024-54413 is a Cross-Site Request Forgery (CSRF) vulnerability in the brandt-net Display Future Posts WordPress plugin that leads to Stored Cross-Site Scripting (XSS). The flaw affects all versions of display-future-posts up to and including 0.2.3. An attacker can craft a malicious request that, when triggered by an authenticated administrator, injects persistent JavaScript into the plugin's stored content. The injected payload then executes in the browser of any user who views the affected page. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.
Critical Impact
Successful exploitation allows attackers to inject persistent JavaScript into a WordPress site by tricking an authenticated administrator into visiting a malicious page, leading to session theft, content manipulation, or further account compromise.
Affected Products
- brandt-net Display Future Posts WordPress plugin
- All versions from n/a through 0.2.3
- WordPress installations using the display-future-posts plugin

Technical Details for CVE-2024-54413
Vulnerability Analysis
The Display Future Posts plugin fails to validate the origin of state-changing HTTP requests. The plugin does not implement WordPress nonce verification on form submissions that modify stored plugin data. As a result, an attacker can craft an HTML page that submits a forged request to the plugin's settings or content endpoints on behalf of a logged-in administrator.
Because the forged request writes attacker-controlled input directly into stored content without sufficient output encoding, the payload is persisted in the database. When any user later loads the page rendering that content, the injected script executes in their browser context. This combines CSRF with Stored XSS, producing a single-click compromise path against the WordPress site.
User interaction is required because the administrator must visit the attacker-controlled page or click a malicious link. The attack scope is changed because the injected script runs in a different security context than the originating vulnerable component.
Root Cause
The root cause is missing CSRF protection on plugin endpoints that accept and store user-supplied input. WordPress provides the wp_nonce_field() and check_admin_referer() APIs to prevent this class of attack, but the affected plugin versions do not apply them consistently. The lack of input sanitization and output encoding on the stored value compounds the issue into a Stored XSS.
Attack Vector
The attack is network-based and requires the victim to be authenticated to the WordPress admin interface. The attacker hosts a page containing a hidden form or JavaScript that auto-submits a POST request to the vulnerable plugin endpoint on the target WordPress site. When the administrator visits the attacker's page, the browser submits the request along with the administrator's session cookies. The plugin processes the request as legitimate and stores the malicious payload, which is later rendered to site visitors.
The vulnerability mechanism is described in the Patchstack Vulnerability Advisory. No public proof-of-concept code is currently available.
Detection Methods for CVE-2024-54413
Indicators of Compromise
- Unexpected <script> tags, event handler attributes such as onerror=, or obfuscated JavaScript stored in Display Future Posts plugin settings or content
- WordPress access logs showing POST requests to plugin endpoints with HTTP Referer headers from external or unrelated domains
- New or modified WordPress administrator accounts created shortly after suspicious admin sessions
- Browser console errors or unexpected outbound requests when rendering pages that use the plugin
Detection Strategies
- Inventory all WordPress sites and identify installations of the display-future-posts plugin at version 0.2.3 or earlier
- Audit wp_options and post metadata for unexpected HTML or JavaScript content associated with the plugin
- Review web server logs for cross-origin POST requests to wp-admin URLs that lack a valid nonce parameter
Monitoring Recommendations
- Deploy a web application firewall (WAF) rule to block requests to WordPress admin endpoints with missing or invalid nonce tokens
- Alert on administrator session activity originating from unusual referrers or geolocations
- Monitor file integrity and database changes on WordPress installations, with focus on plugin-controlled tables and options
How to Mitigate CVE-2024-54413
Immediate Actions Required
- Identify all WordPress sites running the Display Future Posts plugin and disable the plugin if a patched version is not available
- Remove any suspicious stored content from the plugin's data and rotate administrator credentials if compromise is suspected
- Restrict access to wp-admin by IP allowlist where operationally feasible
Patch Information
At the time of NVD publication, the Patchstack advisory lists all versions through 0.2.3 as affected and does not identify a fixed release. Administrators should remove or replace the plugin until the vendor publishes a patched version that implements nonce verification and output encoding.
Workarounds
- Deactivate and uninstall the display-future-posts plugin until a vendor patch is released
- Configure a WAF to enforce same-origin checks on POST requests to WordPress admin URLs
- Train administrators to log out of WordPress sessions before browsing untrusted sites and to use a dedicated browser profile for admin tasks
- Apply Content Security Policy (CSP) headers to limit execution of inline scripts on WordPress-rendered pages
# Example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate display-future-posts
wp plugin uninstall display-future-posts
