light0011 cms is a news content management system built on ThinkPHP that allows users to publish articles with rich media. An unauthenticated server-side request forgery vulnerability in the UEditor image-fetching component allows attackers to make arbitrary HTTP requests from the server, read internal service responses, and publish those contents publicly—potentially exposing internal administrative interfaces and credentials.

## Technical details

The vulnerability is a server-side request forgery (SSRF) in the UEditor catchimage endpoint (Public/ueditor/php/controller.php, lines 15–45). The endpoint accepts unauthenticated requests with a source[] parameter containing arbitrary URLs, which are fetched by the Uploader class without IP allowlisting, DNS rebinding protection, or redirect validation. The vulnerable Uploader.class.php code (lines 182–210) calls get_headers() and readfile() on attacker-supplied URLs; content-type filtering is bypassed by appending a fragment like #allowed.png, and the fetched response body is written to a public web directory. An attacker can probe internal services, extract response bodies, and republish them via the returned public URL, exposing admin interfaces and credentials.
