CVE-2026-122008 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 5.3 (medium) and affects oqtane.framework; fixed in 10.3.0.

## Summary

Oqtane Framework, before version 10.3.0, has a server-side request forgery flaw in its file upload from URL function that lets a logged-in registered user make the server fetch arbitrary URLs. Attackers can use this remotely to request internal resources, such as cloud metadata services or localhost-only management interfaces, and save the responses as files to retrieve, which can expose sensitive internal data or reveal internal hosts and ports.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- oqtane oqtane.framework: from 1.0.0, fixed in 10.3.0

## Description

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.
