CVE-2026-102980

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.
