{"id":"CVE-2026-104968","summary":"Plane: Cross-workspace member enumeration via /api/workspaces/{slug}/entity-search/","details":"Plane is an open-source project management tool. Prior to 1.4.0, GET /api/workspaces/{slug}/entity-search/?query_type=user_mention returns workspace-member display names, UUIDs, and avatar URLs to any authenticated user who knows the workspace slug, even when the caller is not a workspace member. The endpoint also exposes ProjectMember rows under the same condition. SearchEndpoint in apps/api/plane/app/views/search/base.py inherits BaseAPIView with only permission_classes = [IsAuthenticated] and performs no workspace-membership check. This issue is fixed in 1.4.0.","aliases":["GHSA-32q3-mqpc-3mhv"],"modified":"2026-10-07T02:47:26.515603533Z","published":"2026-10-05T16:56:50.909Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104968.json"},"references":[{"type":"WEB","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/104xxx/CVE-2026-104968.json"},{"type":"ADVISORY","url":"https://github.com/makeplane/plane/security/advisories/GHSA-32q3-mqpc-3mhv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104968"},{"type":"FIX","url":"https://github.com/makeplane/plane/commit/28ae25b564351abaf8b36d4a3ba6d32f80fbf075"},{"type":"FIX","url":"https://github.com/makeplane/plane/pull/9296"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/makeplane/plane","events":[{"introduced":"0"},{"fixed":"28ae25b564351abaf8b36d4a3ba6d32f80fbf075"},{"fixed":"917b23a6c16d93fc00cef67900eff2755e8b13f7"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.3.1","v1.3.0","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.28.0","v0.27.1","v0.27.0","v0.26.1","v0.26.0","v0.25.3","v0.25.2","v0.25.1","v0.25.0","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/cve-osv-conversion/osv-output/CVE-2026-104968.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
