Why this deserves its current priority

CVSS is 7.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/ansible-automation-platform-25/hub-rhel8, Red Hat/ansible-automation-platform-26/hub-rhel9, Red Hat/ansible-automation-platform-27/hub-rhel9.
  2. 2Review the reported fix. Source-reported workaround: The following practices would help for avoiding exposure and mitigate this flaw: 1. Ensure that GALAXY_ENABLE_LEGACY_ROLES is set to False (the default) in your Galaxy/Hub configuration. This prevents the v1 API routes from being registered, making the vulnerable endpoint entirely unreachable. 2. If legacy role support must be enabled, restrict access to the Galaxy/Hub API to trusted users only. The vulnerability requires authentication, so limiting who can authenticate reduces exposure. 3. Monitor import activity for suspicious git references containing shell metacharacters in branch or tag names.

Upstream source description

A command injection vulnerability was found in galaxy_ng. The do_git_checkout() function in the legacy role import API (v1) interpolates unsanitized git ref names (branch/tag names) into shell commands executed via subprocess.run() with shell=True. An authenticated user who controls a git repository can create a branch or tag with shell metacharacters in the name to achieve remote code execution on the pulp worker. The vulnerable endpoint is only reachable when GALAXY_ENABLE_LEGACY_ROLES is set to True, which is not the default configuration.
