{"id":"CVE-2026-105637","summary":"Plane: Cross-Project Asset Hijacking via 'ProjectBulkAssetEndpoint' (sibling of CVE-2026-46558)","details":"Plane is an open-source project management tool. 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.","aliases":["GHSA-r2hw-fff3-pjwp"],"modified":"2026-10-06T02:47:23.577212069Z","published":"2026-10-05T18:04:02.780Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105637.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105637.json"},{"type":"FIX","url":"https://github.com/makeplane/plane/commit/15e835710c7f938e0fae9c0ee77bb8162ff436a0"},{"type":"FIX","url":"https://github.com/makeplane/plane/pull/9495"},{"type":"WEB","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0"},{"type":"ADVISORY","url":"https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105637"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/makeplane/plane","events":[{"introduced":"0"},{"fixed":"917b23a6c16d93fc00cef67900eff2755e8b13f7"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.3.1","v1.3.0","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/osv-test-cve-osv-conversion/osv-output/CVE-2026-105637.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
