In 1.3.1 and earlier, EntityAssetEndpoint at the public project asset endpoint /api/public/assets/v2/anchor/{anchor}/ requires authentication for write operations but does not verify workspace or project membership. An authenticated user who knows a published project's public DeployBoard.anchor can create FileAsset records in that project and soft-delete existing assets by identifier, allowing cross-workspace file injection, storage abuse, and data loss. The issue is fixed in version 1.4.0.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9288","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","tags":[]}],"exploitRefs":[{"url":"https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9288","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-8688-h9x2-v83m","tags":[]}],"hasPoc":true,"ai":null}
