{"id":"GHSA-p3hx-pwf3-j8wr","summary":"Nautobot: GitRepository.current_head field should not be writable through REST API","details":"### Impact\n\nA user with access to add/change a GitRepository record could use the REST API to directly set the `current_head` field on the record, which was not intended to be user-editable. Doing so could cause Nautobot's local clone(s) of the relevant repository to checkout a commit other than the latest commit on the specified `branch` (resulting in misleading state), or potentially to be unable to make use of the repository at all (until manually remediated) due to the `current_head` pointing to a nonexistent commit hash or malformed value.\n\n### Patches\n\nThe issue has been remediated in Nautobot v2.4.33 and 3.1.2.\n\n\n### Workarounds\n\nNote that many of the same end-result symptoms could be caused by a user with the same level of access simply changing the `branch` or `remote_url` of a GitRepository rather than crafting the `current_head`. Administrators are encouraged to carefully review which users are granted permissions to create and modify GitRepository records.\n\n\n### References\n\n- 2.4.33 (\u003ca href=\"https://github.com/nautobot/nautobot/commit/9deddfc91ad9260ad17b5e20084e9e2d15be3609\"\u003epatch\u003c/a\u003e)\n- 3.1.2 (\u003ca href=\"https://github.com/nautobot/nautobot/commit/c46f97040b2bde4320be36b23577f19a8bcbd8c3\"\u003epatch\u003c/a\u003e)","aliases":["CVE-2026-44798","PYSEC-2026-2228"],"modified":"2026-07-13T07:26:52.275842901Z","published":"2026-05-13T15:31:04Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-05-13T15:31:04Z","nvd_published_at":"2026-05-28T18:16:34Z","cwe_ids":["CWE-471","CWE-749"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/nautobot/nautobot/security/advisories/GHSA-p3hx-pwf3-j8wr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44798"},{"type":"WEB","url":"https://github.com/nautobot/nautobot/commit/9deddfc91ad9260ad17b5e20084e9e2d15be3609"},{"type":"WEB","url":"https://github.com/nautobot/nautobot/commit/c46f97040b2bde4320be36b23577f19a8bcbd8c3"},{"type":"PACKAGE","url":"https://github.com/nautobot/nautobot"},{"type":"WEB","url":"https://github.com/nautobot/nautobot/releases/tag/v2.4.33"},{"type":"WEB","url":"https://github.com/nautobot/nautobot/releases/tag/v3.1.2"}],"affected":[{"package":{"name":"nautobot","ecosystem":"PyPI","purl":"pkg:pypi/nautobot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0a2"},{"fixed":"3.1.2"}]}],"versions":["3.0.0","3.0.0a2","3.0.0a3","3.0.0rc1","3.0.0rc2","3.0.1","3.0.10","3.0.11","3.0.2","3.0.3","3.0.4","3.0.5","3.0.6","3.0.7","3.0.8","3.0.9","3.1.0","3.1.0a1","3.1.0a2","3.1.0a3","3.1.0a4","3.1.0a5","3.1.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-p3hx-pwf3-j8wr/GHSA-p3hx-pwf3-j8wr.json"}},{"package":{"name":"nautobot","ecosystem":"PyPI","purl":"pkg:pypi/nautobot"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.33"}]}],"versions":["1.0.0","1.0.0a1","1.0.0a2","1.0.0b1","1.0.0b2","1.0.0b3","1.0.0b4","1.0.1","1.0.2","1.0.3","1.1.0","1.1.1","1.1.2","1.1.3","1.1.4","1.1.5","1.1.6","1.2.0","1.2.1","1.2.10","1.2.11","1.2.2","1.2.3","1.2.4","1.2.5","1.2.6","1.2.7","1.2.8","1.2.9","1.3.0","1.3.1","1.3.10","1.3.2","1.3.3","1.3.4","1.3.5","1.3.6","1.3.7","1.3.8","1.3.9","1.4.0","1.4.1","1.4.10","1.4.2","1.4.3","1.4.4","1.4.5","1.4.7","1.4.8","1.4.9","1.5.0","1.5.1","1.5.10","1.5.11","1.5.12","1.5.13","1.5.14","1.5.15","1.5.16","1.5.17","1.5.18","1.5.19","1.5.2","1.5.20","1.5.21","1.5.22","1.5.23","1.5.24","1.5.3","1.5.4","1.5.5","1.5.6","1.5.7","1.5.8","1.5.9","1.6.0","1.6.1","1.6.10","1.6.11","1.6.12","1.6.13","1.6.14","1.6.15","1.6.16","1.6.17","1.6.18","1.6.19","1.6.2","1.6.20","1.6.21","1.6.22","1.6.23","1.6.24","1.6.25","1.6.26","1.6.27","1.6.28","1.6.29","1.6.3","1.6.30","1.6.31","1.6.32","1.6.4","1.6.5","1.6.6","1.6.7","1.6.8","1.6.9","2.0.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.1.0","2.1.0b1","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5","2.1.6","2.1.7","2.1.8","2.1.9","2.2.0","2.2.0b1","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.2.6","2.2.7","2.2.8","2.2.9","2.3.0","2.3.0b1","2.3.1","2.3.10","2.3.11","2.3.12","2.3.13","2.3.14","2.3.15","2.3.15b1","2.3.16","2.3.2","2.3.3","2.3.4","2.3.5","2.3.6","2.3.7","2.3.8","2.3.9","2.4.0","2.4.0b1","2.4.1","2.4.10","2.4.11","2.4.12","2.4.13","2.4.14","2.4.15","2.4.16","2.4.17","2.4.18","2.4.19","2.4.2","2.4.20","2.4.21","2.4.22","2.4.23","2.4.24","2.4.25","2.4.26","2.4.27","2.4.28","2.4.29","2.4.3","2.4.30","2.4.31","2.4.32","2.4.4","2.4.5","2.4.6","2.4.7","2.4.8","2.4.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-p3hx-pwf3-j8wr/GHSA-p3hx-pwf3-j8wr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H"}]}
