{"id":"CVE-2026-104962","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-104962","generatedAt":"2026-10-28T03:41:50.567Z","title":"Plane is an open-source project management tool.","description":"Plane is an open-source project management tool. 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.","published":"2026-10-05T17:17:12.000Z","lastModified":"2026-10-05T19:17:15.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00303,"percentile":0.22881,"date":"2026-10-27","history":[{"date":"2026-10-06","score":0.00303,"percentile":0.21027}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.30%).
