Official Description

Turborepo is a high-performance build system for JavaScript and TypeScript codebases. Prior to 2.9.14, Turborepo's self-hosted login and SSO browser flows did not validate a CSRF state value on the localhost callback. While the CLI was waiting for authentication, a malicious web page could send a request to the local callback server with an attacker-controlled token. If accepted before the legitimate callback, the CLI could complete login with the wrong credentials. This affects users authenticating the turbo CLI against self-hosted remote cache/auth endpoints. Vercel-hosted login flows using device authorization are not affected. This vulnerability is fixed in 2.9.14.
