CVE-2026-79717 Galaxy_ng: galaxy_ng: blind ssrf via namespace avatar_url with no private-address restriction

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.

Exploitable remotely over the network, with an ordinary account and without any user action; the impact on data or service is limited.
