Published Oct 5, 2026CWE-200EPSS 0.25%

Overview

CVE-2026-104963 is a medium-severity vulnerability. It was published on October 5, 2026 and has a CVSS 3.1 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Plane is an open-source project management tool. Prior to 1.4.0, GET /api/workspaces/{slug}/cycles/ through WorkspaceCyclesEndpoint and GET /api/workspaces/{slug}/modules/ through WorkspaceModulesEndpoint return records from every project in a workspace without checking whether the requester belongs to each project. Any authenticated workspace member, including a Guest with access to only one project, can enumerate names, descriptions, sprint dates, issue counts, progress snapshots, external integration IDs, linked URLs, and member lists for cycles and modules in private projects. The sibling WorkspaceLabelsEndpoint and WorkspaceStatesEndpoint apply the correct project__project_projectmember__member=request.user filter, making the cycle and module endpoints inconsistent outliers. This issue is fixed in 1.4.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
