What is CVE-2026-79717?
CVE-2026-79717 is a medium-severity server-side request forgery vulnerability in Red Hat Ansible Automation Platform 2, published on 25 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
A server-side request forgery (SSRF) vulnerability was found in galaxy_ng, the Ansible Galaxy server plugin for Pulp. An authenticated user with namespace management permissions can set a namespace avatar URL to an arbitrary address, including internal networks, loopback, or cloud instance metadata endpoints. A background worker fetches that URL without checking the destination, which lets the attacker probe internal services and enumerate reachable IP addresses. The HTTP client is also configured without an overall timeout, so a slow or non-responsive target can pin workers and cause a denial of service.
Weakness: CWE-918
