{"id":"PYSEC-2026-2486","summary":"Galaxy NG: command injection vulnerability","details":"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.","aliases":["CVE-2026-12398","GHSA-6hw7-j4jw-wpff"],"modified":"2026-07-13T16:32:37.446342238Z","published":"2026-07-13T15:46:17.919996Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12398"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-12398"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2489180"},{"type":"PACKAGE","url":"https://github.com/ansible/galaxy_ng"},{"type":"PACKAGE","url":"https://pypi.org/project/galaxy-ng"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-6hw7-j4jw-wpff"}],"affected":[{"package":{"name":"galaxy-ng","ecosystem":"PyPI","purl":"pkg:pypi/galaxy-ng"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.9.2"}]}],"versions":["4.2.0","4.2.0a10","4.2.0a12","4.2.0a3","4.2.0a4","4.2.0a5","4.2.0a6","4.2.0a7","4.2.0a8","4.2.0a9","4.2.0b1","4.2.0b2","4.2.0b3","4.2.0rc1","4.2.0rc2","4.2.0rc3","4.2.1","4.2.2","4.2.3","4.2.3b1","4.2.4","4.2.5","4.2.6","4.2.7","4.2.8","4.3.0","4.3.0a1","4.3.0a2","4.3.0b4","4.3.1","4.3.2","4.3.3","4.3.4","4.3.5","4.4.0","4.4.0a1","4.4.0a2","4.4.0b1","4.4.0b2","4.4.1","4.4.2","4.4.3","4.4.4","4.4.5","4.5.0","4.5.0b1","4.5.1","4.5.2","4.5.3","4.5.4","4.5.5","4.6.0","4.6.1","4.6.2","4.6.3","4.6.4","4.6.5","4.6.6","4.7.0","4.7.1","4.7.2","4.7.3","4.8.0","4.8.1","4.9.0","4.9.1","4.9.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/galaxy-ng/PYSEC-2026-2486.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
