{"id":"CVE-2026-102980","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-102980","generatedAt":"2026-10-28T04:18:00.072Z","title":"Plane is an open-source project management tool.","description":"Plane is an open-source project management tool. Prior to 1.4.0, PageVersionEndpoint in apps/api/plane/app/views/page/version.py scopes page-version lookups by workspace and page identifiers but not by the project_id from the URL. ProjectPagePermission likewise derives the caller's role from the URL project while resolving the requested page workspace-wide, so a member of one project can use that project's identifier to read description_html for a public page in another project in the same workspace. The affected path is read-only and does not enable cross-project page modification. This issue is fixed in version 1.4.0.","published":"2026-10-14T20:17:29.000Z","lastModified":"2026-10-15T15:17:20.000Z","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-639"],"affected":[],"epss":{"score":0.00386,"percentile":0.32521,"date":"2026-10-27","history":[{"date":"2026-10-15","score":0.00304,"percentile":0.21623}]},"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 (0.39%).
