CVE-2022-24128 — Timescale TimescaleDB 1.x and 2.x before 2.5.2 may allow privilege escalation during extension installation

High CVSS 8

Timescale TimescaleDB 1.x and 2.x before 2.5.2 may allow privilege escalation during extension installation. The installation process uses commands such as CREATE x IF NOT EXIST that allow an unprivileged user to precreate objects. These objects will be used by the installer (which executes as Superuser), leading to privilege escalation. In order to be able to take advantage of this, an unprivileged user would need to be able to create objects in a database and then get a Superuser to install TimescaleDB into their database. (In the fixed versions, the installation aborts when it finds that an object already exists.)

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.
