Prior to 1.4.0, the GraphQL joinProject mutation lets any workspace member add themselves to any project in that workspace including network=0 (secret/private) projects they were never invited to and grants them a full Member role (read + write). The resolver checks only workspace-level membership/role and never checks the target project's visibility (network). This collapses project-level tenant isolation within a workspace: a low-privilege member can read and modify confidential data in every private project. This issue is fixed in 1.4.0.","state":0,"publishedAt":"2026-10-05T17:57:22.672+00:00","modifiedAt":"2026-10-05T19:13:21.788+00:00","affected":[{"ecosystem":"Vendor product","name":"plane","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"makeplane\",\n                    \"product\": \"plane\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":8.7,"severity":"HIGH"}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm","https://github.com/makeplane/plane/pull/9333","https://github.com/makeplane/plane/commit/e1ef42023ab66b5e722a8750e1bc5ba0d413a3ee","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105632","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105632","identifiers":["CVE-2026-105632"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
