CVE-2026-6983 Details
Description
A vulnerability was identified in pagekit up to 1.0.18. Affected by this issue is some unknown functionality of the file /index.php/admin/system/update/download. The manipulation of the argument url leads to server-side request forgery. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
A server-side request forgery (SSRF) vulnerability has been identified in Pagekit CMS versions through 1.0.18. The issue arises in the system update download endpoint, where the 'url' parameter is accepted without proper validation. This vulnerability allows authenticated administrators to exploit the endpoint for various malicious activities, such as reading arbitrary local files, scanning internal network services, accessing cloud metadata to steal credentials, and attacking internal services via a pivot point.
It is recommended to implement a URL scheme whitelist, allowing only HTTPS from trusted domains, and to replace 'fopen' with 'cURL' for better control over requests. Additionally, block private IP addresses to prevent internal network access.
