CVE-2024-54257 Overview
CVE-2024-54257 is a reflected Cross-Site Scripting (XSS) vulnerability affecting the Molefed tydskrif WordPress theme through version 1.1.3. The flaw stems from improper neutralization of user-supplied input during web page generation, classified under [CWE-79]. Attackers can craft malicious URLs that, when clicked by an authenticated or unauthenticated user, execute arbitrary JavaScript in the victim's browser session. The scope change indicator means the executed script can affect resources beyond the vulnerable component's security context.
Critical Impact
Successful exploitation enables session hijacking, credential theft, and unauthorized actions performed on behalf of the targeted user within the WordPress site.
Affected Products
- Molefed tydskrif WordPress theme versions through 1.1.3
- WordPress sites with the vulnerable theme active
- Any user session interacting with crafted reflected XSS payloads

Technical Details for CVE-2024-54257
Vulnerability Analysis
The tydskrif theme fails to sanitize or encode user-controlled input before reflecting it into HTML responses. When a request parameter containing JavaScript reaches a vulnerable rendering path, the theme echoes that value directly into the page output. Browsers then parse the injected markup as executable script.
The attack requires user interaction, typically by tricking a victim into clicking a crafted link. Because the vulnerability has a changed scope, injected code can interact with cookies, tokens, and DOM elements belonging to the WordPress application context. This expands the impact beyond the immediate request handler.
The EPSS probability for this issue is 0.27%, placing it in the 18th percentile of exploited vulnerabilities. No public proof-of-concept exploit or CISA Known Exploited Vulnerabilities (KEV) listing is currently associated with CVE-2024-54257.
Root Cause
The root cause is missing output encoding on one or more theme template files that consume HTTP request data. WordPress provides escaping functions such as esc_html(), esc_attr(), and wp_kses() that the theme does not apply to reflected parameters. Developer reliance on raw input variables produces the injection sink described by [CWE-79].
Attack Vector
Exploitation occurs over the network and requires the victim to load an attacker-supplied URL. The attacker embeds a JavaScript payload within a query parameter processed by the vulnerable theme component. The server reflects the payload into the response, and the victim's browser executes it under the origin of the WordPress site.
The vulnerability mechanism is described in prose because no verified public exploit code is available. See the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2024-54257
Indicators of Compromise
- HTTP request logs containing URL parameters with <script>, javascript:, or HTML event handler strings such as onerror= and onload=
- Unexpected outbound requests from user browsers to attacker-controlled domains following clicks on links referencing the WordPress site
- WordPress access logs showing repeated requests to theme pages with encoded payloads (%3Cscript%3E, %22%3E%3Csvg)
Detection Strategies
- Deploy a Web Application Firewall (WAF) rule set tuned to flag reflected XSS patterns targeting WordPress theme endpoints
- Implement Content Security Policy (CSP) violation reporting to capture inline script execution attempts originating from reflected input
- Correlate authentication anomalies, such as session reuse from unexpected IP addresses, with prior click events on suspicious URLs
Monitoring Recommendations
- Monitor WordPress access logs for query strings containing HTML or JavaScript syntax against tydskrif theme paths
- Alert on administrator session tokens being used from geographies inconsistent with normal activity
- Track referer headers pointing to phishing or typosquatted domains that link into the WordPress site
How to Mitigate CVE-2024-54257
Immediate Actions Required
- Identify all WordPress sites running the Molefed tydskrif theme at version 1.1.3 or earlier
- Deactivate the vulnerable theme until a patched version is confirmed installed
- Force a password reset for administrative users and rotate WordPress authentication keys and salts in wp-config.php
- Review WordPress audit logs for any administrative actions that may indicate successful exploitation
Patch Information
No fixed version is documented in the available NVD data for CVE-2024-54257. The vulnerability affects releases through 1.1.3. Administrators should consult the Patchstack Vulnerability Report for the latest remediation status and apply any vendor-released update once available.
Workarounds
- Replace the tydskrif theme with an actively maintained alternative if no patch is released
- Deploy a WAF rule set that blocks reflected XSS payloads targeting WordPress theme parameters
- Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to known-good origins
- Educate users and administrators to avoid clicking unsolicited links referencing the WordPress site
# Example restrictive Content Security Policy header for WordPress
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"
