What is CVE-2026-48790?
CVE-2026-48790 is a medium-severity vulnerability in tursodatabase turso-cli, published on 11 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
