Plain English Summary

AI-powered analysis for quick understanding

An attacker can steal OAuth access tokens for any user by simply providing their user ID and a provider name, allowing them to access third-party services without needing to log in. This vulnerability affects versions of SimStudio below 0.5.74 and does not require any authentication, making it particularly dangerous.

Technical Description

On SimStudio version below to 0.5.74, the `/api/auth/oauth/token` endpoint contains a code path that bypasses all authorization checks when provided with `credentialAccountUserId` and `providerId` parameters. An unauthenticated attacker can retrieve OAuth access tokens for any user by supplying their user ID and a provider name, effectively stealing credentials to third-party services.
