Turso CLI JWT Exposure via Insecure File Permissions

Publication date: 2026-08-11

Last updated on: 2026-08-11

Assigner: GitHub, Inc.

Description
Turso CLI is the command line interface (CLI) to the open-source database Turso. Versions prior to 1.0.26 persist the user's Turso platform JWT to `settings.json` using Viper's default `configPermissions` of `0o644`, leaving the credential file world-readable on standard Linux and macOS systems. Any other local UID on the host can read the file and recover the platform JWT, which grants full Turso platform access scoped to the user's organizations. Version 1.0.26 patches the issue.

Executive Summary

Turso CLI versions before 1.0.26 store the user's Turso platform JWT in a settings.json file with overly permissive permissions (0o644). This allows any local user on the system to read the token, potentially granting unauthorized access to the user's Turso platform account.

Detection Guidance

Check if the settings.json file in the Turso CLI configuration directory has overly permissive settings. Run: ls -l ~/.turso/settings.json to verify permissions. If permissions show 644 or similar, the file is world-readable and vulnerable.

Impact Analysis

An attacker with local access could read the JWT token and perform actions like creating databases, rotating credentials, exfiltrating data, or modifying billing across all organizations the user belongs to.

Mitigation Strategies

Upgrade to Turso CLI version 1.0.26 or later. If unable to upgrade, manually set restrictive permissions on the settings.json file and its directory using: chmod 600 ~/.turso/settings.json and chmod 700 ~/.turso.
