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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/makeplane/plane/commit/28ae25b564351abaf8b36d4a3ba6d32f80fbf075","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9296","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-32q3-mqpc-3mhv","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-32q3-mqpc-3mhv","tags":[]}],"exploitRefs":[{"url":"https://github.com/makeplane/plane/commit/28ae25b564351abaf8b36d4a3ba6d32f80fbf075","tags":[]},{"url":"https://github.com/makeplane/plane/pull/9296","tags":[]},{"url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-32q3-mqpc-3mhv","tags":[]},{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-32q3-mqpc-3mhv","tags":[]}],"hasPoc":true,"ai":null}
