CVE-2023-22836Network attack vector

Cross-tenant group-name disclosure via missing authorization

Published Jan 29, 2024 · Updated Jun 17, 2025

Information disclosure in Palantir Foundry Linter before 2.278.0 allows remote authenticated users to view renamed group names. The service does not enforce tenant-scoped authorization when exposing a changed group name, so the renamed value becomes visible across tenants. Exploitation requires a multi-tenant stack user to operate Linter, rename a group from its default, and interact with another tenant's view.
