CVE-2024-54419 Overview
CVE-2024-54419 is a Cross-Site Request Forgery (CSRF) vulnerability in the ui-slider-filter-by-price WordPress plugin developed by chenyenming. The flaw affects all versions of UI Slider Filter By Price up to and including 1.1. An attacker can craft a malicious web page that, when visited by an authenticated site administrator, triggers unauthorized state-changing actions on the WordPress site. The vulnerability is categorized under [CWE-352] Cross-Site Request Forgery. Successful exploitation requires user interaction, such as clicking a crafted link or loading an attacker-controlled page.
Critical Impact
An attacker can forge authenticated requests against WordPress sites running the vulnerable plugin, resulting in limited integrity and availability impact when a privileged user is tricked into visiting a malicious page.
Affected Products
- WordPress plugin: ui-slider-filter-by-price (UI Slider Filter By Price) by chenyenming
- All versions from initial release through 1.1
- WordPress sites with the plugin installed and activated

Technical Details for CVE-2024-54419
Vulnerability Analysis
The vulnerability stems from missing or insufficient CSRF protections in the UI Slider Filter By Price plugin. WordPress provides nonce mechanisms such as wp_nonce_field() and check_admin_referer() to validate the origin of state-changing requests. The affected plugin does not consistently validate these tokens on sensitive request handlers. An attacker can therefore craft an HTTP request that mirrors a legitimate administrative action and cause an authenticated victim's browser to submit it.
The attack requires social engineering. A logged-in administrator must visit an attacker-controlled page or click a crafted link while their WordPress session is active. Because the browser automatically attaches session cookies, the forged request executes with the victim's privileges.
Root Cause
The root cause is the absence of anti-CSRF token verification on plugin request handlers. Without a nonce check, the server cannot distinguish between legitimate admin-initiated requests and cross-origin forged requests carrying the victim's session cookies. This maps to [CWE-352] Cross-Site Request Forgery.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts a page containing a hidden form or JavaScript that auto-submits a request to the target WordPress site. When an authenticated administrator loads the page, the browser transmits session cookies with the forged request, and the plugin processes the action without verifying its origin. Refer to the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2024-54419
Indicators of Compromise
- Unexpected changes to plugin configuration or settings within the WordPress admin dashboard.
- Web server access logs showing POST requests to plugin endpoints with Referer headers pointing to external, untrusted domains.
- Administrator account activity originating from unusual browser sessions or immediately following external link clicks.
Detection Strategies
- Review WordPress audit logs for state-changing plugin actions that do not correlate with legitimate administrator workflows.
- Inspect HTTP request logs for requests to ui-slider-filter-by-price handlers missing valid _wpnonce parameters.
- Correlate administrative actions with authentication events to identify requests triggered outside active admin sessions.
Monitoring Recommendations
- Enable a WordPress activity logging plugin to capture plugin configuration changes with timestamps and originating IP addresses.
- Monitor web application firewall (WAF) telemetry for cross-origin requests targeting WordPress admin endpoints.
- Alert on anomalous Referer or Origin header values on requests to plugin administrative routes.
How to Mitigate CVE-2024-54419
Immediate Actions Required
- Deactivate and remove the UI Slider Filter By Price plugin if no vendor patch is available for your installed version.
- Restrict WordPress administrator sessions to dedicated browsers or browser profiles that do not visit untrusted sites.
- Enforce strong session policies, including short session lifetimes and mandatory re-authentication for sensitive operations.
Patch Information
At the time of publication, the vulnerability affects UI Slider Filter By Price versions up to and including 1.1, and no fixed version is identified in the referenced advisory. Consult the Patchstack Vulnerability Report for the current patch status and monitor the WordPress plugin repository for updates.
Workarounds
- Deploy a web application firewall rule that blocks requests to the plugin's endpoints when Referer or Origin headers do not match the site's origin.
- Require administrators to authenticate through a separate browser profile to reduce the likelihood of active sessions during casual browsing.
- Limit the number of accounts with administrator privileges to reduce the exploitable population.
