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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-284"],"references":["https://github.com/makeplane/plane/commit/e1ef42023ab66b5e722a8750e1bc5ba0d413a3ee","https://github.com/makeplane/plane/pull/9333","https://github.com/makeplane/plane/releases/tag/v1.4.0","https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm","https://github.com/makeplane/plane/security/advisories/GHSA-45hc-q4mw-jhxm"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105632","score":0.00312,"percentile":0.23892,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
