{"id":"CVE-2026-35477","summary":"InvenTree has SSTI in PART_NAME_FORMAT bypasses CVE-2026-27629 fix via {% if part.pk %} sandbox escape","details":"InvenTree is an Open Source Inventory Management System. From 1.2.3 to 1.2.6, the fix for CVE-2026-27629 upgraded the PART_NAME_FORMAT validator to use jinja2.sandbox.SandboxedEnvironment. However, the actual renderer in part/helpers.py was not updated and still uses the non-sandboxed jinja2.Environment. Additionally, the validator uses a dummy Part instance with pk=None, which allows conditional template expressions to behave differently during validation versus production rendering. A staff user with settings access can craft a template that passes validation but executes arbitrary code during rendering. This issue requires access by a user with granted staff permissions. This vulnerability is fixed in 1.2.7 and 1.3.0.","aliases":["GHSA-84jh-x777-8pqq"],"modified":"2026-07-15T01:49:18.059734718Z","published":"2026-04-08T19:20:58.967Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-1336"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35477.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35477.json"},{"type":"ADVISORY","url":"https://github.com/inventree/InvenTree/security/advisories/GHSA-84jh-x777-8pqq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35477"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/inventree/inventree","events":[{"introduced":"12da3b01fc1f32553009fe9041f3bbfca9d55f32"},{"fixed":"01bf60000462fd19d8f939a0561e55e08f38a260"}],"database_specific":{"cpe":"cpe:2.3:a:inventree_project:inventree:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.2.3"},{"fixed":"1.2.7"},{"last_affected":"1.2.6"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"versions":["1.2.6","1.2.5","1.2.4","1.2.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35477.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N"}]}
