✅ Remediation
The containers required to run Discovery can be installed through discoveryctl RPM. See the official documentation for more details. Workaround: To mitigate this Cross-Site Scripting (XSS) vulnerability, ensure that applications utilizing React Router's unstable React Server Components (RSC) APIs only process redirects from trusted sources. Avoiding the use of these unstable APIs in production environments where untrusted redirect sources cannot be guaranteed is also recommended. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Prometheus Exporter Initcontainer/App Sre/Managed Prometheus Exporter Base/Python3X Aiohttp builds), which schedule an initial keep-alive timeout check in connection_made() when keepalive_timeout is greater than zero, lower the default keepalive_timeout from 3630 to 75.0 seconds, and enforce a first-request deadline, closing all 2 injection vectors (idle TCP connections opened without sending request data, trickling partial request data before the first complete HTTP request). Until patched, this is a concern on aiohttp HTTP server deployments directly exposed to network traffic without intermediate timeout enforcement, so place aiohttp instances behind a reverse proxy that actively enforces connection read and idle timeouts before requests arrive. As a compensating measure, configure systemd WatchdogSec and automatic restart directives to monitor daemon responsiveness and restart the aiohttp service if connection exhaustion halts health checks. These controls limit blast radius and contain exploitation, but they do not fix the underlying missing initial request timeout defect — apply the upstream patch to fully remediate.
