Name of the Vulnerable Software and Affected Versions SimStudio versions prior to 0.5.74

Description The /api/auth/oauth/token endpoint in SimStudio has a code path that circumvents authorization checks when provided with the credentialAccountUserId and providerId parameters. An unauthenticated attacker can obtain OAuth access tokens for any user by providing their user ID and a provider name, potentially compromising credentials to third-party services.

Recommendations Update SimStudio to version 0.5.74 or later. As a temporary workaround, restrict access to the /api/auth/oauth/token endpoint.
