CVE-2023-27578 — Galaxy is an open-source platform for data analysis

Critical CVSS 9.1

Galaxy is an open-source platform for data analysis. All supported versions of Galaxy are affected prior to 22.01, 22.05, and 23.0 are affected by an insufficient permission check. Unsupported versions are likely affected as far back as the functionality of Visualizations/Pages exists. Due to this issue, an attacker can modify or delete any Galaxy Visualization or Galaxy Page given they know the encoded ID of it. Additionally, they can copy or import any Galaxy Visualization given they know the encoded ID of it. Patches are available for versions 22.01, 22.05, and 23.0. For the changes to take effect, you must restart all Galaxy server processes. There are no supported workarounds.

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
