CVE intelligence and bounded remediation

CVE-2023-40168 — TurboWarp is a desktop application that compiles scratch projects to JavaScript

High CVSS 7.4

TurboWarp is a desktop application that compiles scratch projects to JavaScript. TurboWarp Desktop versions prior to version 1.8.0 allowed a malicious project or custom extension to read arbitrary files from disk and upload them to a remote server. The only required user interaction is opening the sb3 file or loading the extension. The web version of TurboWarp is not affected. This bug has been addressed in commit `55e07e99b59` after an initial fix which was reverted. Users are advised to upgrade to version 1.8.0 or later. Users unable to upgrade should avoid opening sb3 files or loading extensions from untrusted sources.

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.
