{"id":"CVE-2026-105637","published":"2026-10-05T19:17:17.860","lastModified":"2026-10-05T20:17:11.203","description":"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.","cvssScore":9.6,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/makeplane/plane/commit/15e835710c7f938e0fae9c0ee77bb8162ff436a0","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9495","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp","tags":[]}],"exploitRefs":[{"url":"https://github.com/makeplane/plane/commit/15e835710c7f938e0fae9c0ee77bb8162ff436a0","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9495","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-r2hw-fff3-pjwp","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows a workspace Guest to hijack assets from another project by manipulating asset UUIDs, effectively reassigning ownership and providing a presigned download URL for the hijacked file.","exploitability":"Exploitation is relatively straightforward as it requires a Guest user to provide asset UUIDs from another project, but the attacker must have access to the workspace.","blast_radius":"If exploited, the real-world impact could be significant, as it allows unauthorized access to and potential download of sensitive project assets.","remediation":"Upgrade to version 1.4.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["web","asset-hijack","workspace"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-06T08:44:37.033Z"}}
