CVE-2026-3432 Details
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.
A vulnerability exists in SimStudio versions prior to 0.5.74, specifically in the '/api/auth/oauth/token' endpoint. This vulnerability allows an unauthenticated attacker to bypass authorization checks by using the 'credentialAccountUserId' and 'providerId' parameters. By supplying a user's ID and a provider name, the attacker can obtain OAuth access tokens for that user, effectively stealing credentials for third-party services.
Users are advised to update to SimStudio version 0.5.74 or later.
