{"schema":"threatline.record/2","record":{"id":"CVE-2026-105632","aliases":["GHSA-45hc-q4mw-jhxm"],"summary":"Plane: Broken Access Control - joinProject GraphQL mutation allows self-join into private (secret) projects","details":"Plane is an open-source project management tool. 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.","categories":["Unclassified"],"product":"plane","vendor":"makeplane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105632","source_modified_at":"2026-10-05T19:13:21.788Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"plane","vendor":"makeplane","versions":[{"status":"affected","version":"< 1.4.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm","source_modified_at":"2026-10-05T17:56:31Z","fetched_at":"2026-10-23T21:14:28.314422Z","package":{"ecosystem":"other","name":"makeplane/plane"},"range":"<= 1.3.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm","source_modified_at":"2026-10-05T17:56:31Z","fetched_at":"2026-10-23T21:14:28.314422Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00312,"percentile":0.22922,"score_date":"2026-10-23"},"published_at":"2026-10-05T17:57:22.672Z","modified_at":"2026-10-05T19:13:21.788Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105632","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T19:13:21.788Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm","fetched_at":"2026-10-23T21:14:28.314422Z","source_modified_at":"2026-10-05T17:56:31Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105632","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9333","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/e1ef42023ab66b5e722a8750e1bc5ba0d413a3ee","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":"total","assessed_at":"2026-10-05T19:13:14.016455Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T19:13:21.788Z","content_hash":"45922f4188c2ebb814f9209100c7645a82bb8f8e3b4c295af2003ccfff0b58a9"}}
