Prior to 1.4.0, ProjectBulkAssetEndpoint.post in apps/api/plane/app/views/asset/v2.py retrieves assets using id__in=asset_ids and workspace__slug=slug but does not constrain the query with project_id from the URL. A workspace Guest can provide asset UUIDs from another project in the same workspace and reassign their issue_id, comment_id, page_id, draft_issue_id, or project_id to an entity the attacker controls. Plane then treats the attacker's project as the new owner and provides a presigned download URL for the hijacked file. This issue is fixed in 1.4.0.","state":0,"publishedAt":"2026-10-05T18:04:02.78+00:00","modifiedAt":"2026-10-05T19:09:51.157+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:C/C:H/I:H/A:N","score":9.6,"severity":"CRITICAL"}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp","https://github.com/makeplane/plane/pull/9495","https://github.com/makeplane/plane/commit/15e835710c7f938e0fae9c0ee77bb8162ff436a0","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105637","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105637","identifiers":["CVE-2026-105637"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
