{"id":"CVE-2026-27705","summary":"Plane Vulnerable to Cross-Workspace/Cross-Project Asset Modification via IDOR in ProjectAssetEndpoint.patch","details":"Plane is an an open-source project management tool. Prior to version 1.2.2, the `ProjectAssetEndpoint.patch()` method in `apps/api/plane/app/views/asset/v2.py` (lines 579–593) performs a global asset lookup using only the asset ID (`pk`) via `FileAsset.objects.get(id=pk)`, without verifying that the asset belongs to the workspace and project specified in the URL path. This allows any authenticated user (including those with the GUEST role) to modify the `attributes` and `is_uploaded` status of assets belonging to any workspace or project in the entire Plane instance by guessing or enumerating asset UUIDs. Version 1.2.2 fixes the issue.","aliases":["GHSA-rfj3-8c85-g46j"],"modified":"2026-08-12T03:51:27.690220537Z","published":"2026-02-25T15:51:46.700Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27705.json"},"references":[{"type":"WEB","url":"https://github.com/makeplane/plane/releases/tag/v1.2.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27705.json"},{"type":"ADVISORY","url":"https://github.com/makeplane/plane/security/advisories/GHSA-rfj3-8c85-g46j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27705"},{"type":"FIX","url":"https://github.com/makeplane/plane/commit/9070acbbe81bc02db5c169789da6862d5fc35d96"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/makeplane/plane","events":[{"introduced":"0"},{"fixed":"f53446340b9021c6916259aa9cf772920309415d"},{"fixed":"9070acbbe81bc02db5c169789da6862d5fc35d96"}],"database_specific":{"cpe":"cpe:2.3:a:plane:plane:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.2.2"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.28.0","v0.27.1","v0.27.0","v0.26.1","v0.26.0","v0.25.3","v0.25.2","v0.25.1","v0.25.0","v0.24.0","v0.23.1","v0.23.0","v0.22-dev","v0.21-dev","v0.20-dev","v0.19-dev","v0.18-dev","v0.17-dev","v0.16-dev","v0.15.4-dev","v0.15.3-hotfix","v0.15.2-dev","v0.15.1-dev","v0.15-dev","v0.14.2-dev","v0.14.1-dev","v0.14-dev","v0.13.2-dev","v0.13.1-dev","v0.13-dev","v0.12.2-dev","v0.12.1-dev","v0.12-dev","v0.11-dev","v0.10-dev","v0.9-dev","v0.8-dev","v0.7.1-dev","v0.7-dev","v0.6-dev","v0.5-dev","v0.4-dev","v0.3.1-dev","v0.1-dev"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27705.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U"}]}
