Cross Site Request Forgery (CSRF) vulnerability in CS Cart 4.18.3, allows attackers to add products to a user's comparison list via a crafted HTTP request.

AnalysisAI

Cross-Site Request Forgery in CS-Cart 4.18.3 permits an attacker to silently add arbitrary products to an authenticated user's comparison list by tricking the victim into loading a crafted HTTP request. The impact is confined to unauthorized modification of the comparison list feature - no data exfiltration or account takeover is possible via this vector. No public exploit identified at time of analysis, and the EPSS score of 0.14% (4th percentile) reflects very low real-world exploitation interest.

Technical ContextAI

CS-Cart (cpe:2.3:a:cs-cart:cs-cart:4.18.3:*:*:*:*:*:*:*) is a PHP-based commercial e-commerce platform. CWE-352 (Cross-Site Request Forgery) describes a root cause where a web application accepts state-changing requests without verifying that the request originated from the legitimate user's own session - typically because anti-CSRF tokens are absent or not validated on the endpoint that manages the comparison list. An attacker who can serve content to a victim's browser (e.g., via a malicious link or embedded iframe) can forge a request that the victim's authenticated session will sign, causing the server to act on the attacker's behalf. The vulnerability is specific to version 4.18.3; no CPE data indicates earlier or later versions are confirmed affected.

RemediationAI

No vendor-released patch has been identified at time of analysis - the only available reference is a researcher-authored GitHub disclosure with no corresponding CS-Cart vendor advisory or patched release version. CS-Cart users on version 4.18.3 should monitor the official CS-Cart changelog and security advisories for a fix. As a compensating control, site administrators can consider disabling or restricting access to the product comparison feature if it is not business-critical, which eliminates the attack surface entirely. Additionally, a Web Application Firewall (WAF) rule that enforces the presence of a valid Referer or Origin header on state-changing requests can reduce exposure, though this is not a substitute for proper server-side CSRF token validation. Restricting the comparison list endpoint to authenticated sessions only - if not already the case - limits the attack to scenarios where the victim is logged in.
