Prior to 1.4.0, Plane's dashboard asset endpoints in plane/app/views/asset/v2.py were remediated for two cross-tenant asset IDORs, CVE-2026-27705 and CVE-2026-46558. Those fixes added a membership check and project_id and workspace__slug scoping to the asset endpoints in that file. The Spaces app in plane/space/views/asset.py serves related public-board operations under /api/public/ but was not remediated. Its EntityAssetEndpoint and AssetRestoreEndpoint resolve a DeployBoard from a public anchor and then read or modify FileAsset rows scoped only to the board's workspace, without a membership check or project_id constraint. An attacker can therefore read, overwrite, or restore assets across projects and workspaces. This issue is fixed in 1.4.0.","state":0,"publishedAt":"2026-10-05T17:44:24.414+00:00","modifiedAt":"2026-10-05T18:00:17.007+00:00","affected":[{"ecosystem":"Vendor product","name":"plane","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"makeplane\",\n                    \"product\": \"plane\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-jh4v-88j2-g65v","https://github.com/makeplane/plane/pull/9288","https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104975","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104975","identifiers":["CVE-2026-104975"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
