Prior to 1.4.0, Plane's project update endpoint authorizes the caller against the workspace slug in the request URL but loads the target project globally by UUID without binding it to that workspace. An administrator of one workspace can modify a project in another workspace when the victim project UUID is known. This violates tenant isolation and permits unauthorized cross-workspace changes to project metadata and configuration. This issue is fixed in 1.4.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:N","score":6.8},"cwes":["CWE-639"],"references":["https://github.com/makeplane/plane/commit/9491bdbe46e269611f9dad9cfb5182c2da8ca65a","https://github.com/makeplane/plane/releases/tag/v1.4.0","https://github.com/makeplane/plane/security/advisories/GHSA-pp22-3ghf-949q","https://github.com/makeplane/plane/security/advisories/GHSA-pp22-3ghf-949q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-104964","score":0.00287,"percentile":0.20986,"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).
