{"id":"CVE-2026-27705","state":"PUBLISHED","title":"Plane Vulnerable to Cross-Workspace/Cross-Project Asset Modification via IDOR in ProjectAssetEndpoint.patch","description":"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.","publishedAt":"2026-02-25T15:51:46.700Z","updatedAt":"2026-02-25T20:10:06.766Z","severity":{"score":4.9,"label":"Medium","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["makeplane plane"],"affected":[{"vendor":"makeplane","product":"plane","versions":[{"version":"< 1.2.2","status":"affected"}]}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-rfj3-8c85-g46j","https://github.com/makeplane/plane/commit/9070acbbe81bc02db5c169789da6862d5fc35d96","https://github.com/makeplane/plane/releases/tag/v1.2.2"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27705.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27705","state":"PUBLISHED","datePublished":"2026-02-25T15:51:46.700Z","dateUpdated":"2026-02-25T20:10:06.766Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-23T17:56:51.202Z"},"containers":{"cna":{"title":"Plane Vulnerable to Cross-Workspace/Cross-Project Asset Modification via IDOR in ProjectAssetEndpoint.patch","descriptions":[{"lang":"en","value":"Plane is an an open-source project management tool.
