Prior to 1.4.0, GET /api/v1/workspaces/{slug}/projects/{project_id}/members/ returns the complete project-member roster, including each member's email address, first and last name, display name, avatar, and role. ProjectMemberPermission gates the endpoint, but its SAFE_METHODS branch checks only whether the caller is an active ProjectMember of any project in the workspace and does not bind the check to view.project_id. The view then filters solely by the project_id supplied in the URL. Consequently, any authenticated user who belongs to one project in a workspace, including a Guest, can read the roster of another private project in the same workspace. This issue is fixed in 1.4.0.","categories":["Unclassified"],"product":"plane","vendor":"makeplane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104962","source_modified_at":"2026-10-05T18:35:00.348Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"plane","vendor":"makeplane","versions":[{"version":"< 1.4.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00303,"percentile":0.2186,"score_date":"2026-10-23"},"published_at":"2026-10-05T16:50:27.183Z","modified_at":"2026-10-05T18:35:00.348Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104962","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T18:35:00.348Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104962","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/makeplane/plane/security/advisories/GHSA-w2vf-m9x9-mvmc","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9375","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/5842ca8bf2b984b81c45bf58148a39b348a8995e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-05T18:34:37.833506Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T18:35:00.348Z","content_hash":"816df5088ed2dd9d9d79a44b864f37444033e04a44b098c5c9ef8b7b56c4c604"}}
