Technical details
An Insecure Direct Object Reference (IDOR) exists in the 'POST /api/data-sources/decrypt' endpoint. Unlike other data-source routes in ToolJet, this specific handler lacks the 'ValidateDataSourceGuard' and does not perform organization-level scoping. The underlying 'CredentialsService.getValue()' function retrieves credentials based solely on the provided 'credential_id' without verifying if the requesting user belongs to the organization that owns the secret. An authenticated attacker can exploit this by supplying a 'credential_id' in the request body to receive the plaintext value of secrets like database passwords or OAuth tokens. The issue is fixed in version 3.20.1780-lts.
