Detailsinfo

A vulnerability was found in Oqtane Framework up to 10.2.x. It has been classified as critical. This affects the function HttpClient.GetStreamAsync of the file FileController.cs of the component UploadFile endpoint. The manipulation of the argument url with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Oqtane Framework before 10.3.0 contains a server-side request forgery vulnerability in the UploadFile endpoint of FileController.cs that allows authenticated registered users to make the server fetch arbitrary URLs by supplying a caller-controlled url parameter to HttpClient.GetStreamAsync without validating the scheme, host, or IP address. Attackers can request internal resources such as cloud instance metadata services or localhost-bound management interfaces, save the fetched response as a file in their own user folder, and retrieve it via the download endpoint to exfiltrate sensitive internal data or enumerate internal network hosts and ports.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-122008 since 11/04/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available.
