Title
Helicone Cross-Tenant Provider Key Disclosure via Missing Organization Filter
Summary
Helicone's VaultManager.getDecryptedProviderKeyById() function in the GET /v1/vault/key/{providerKeyId} endpoint fails to validate the requester's organization against the vault key's organization identifier. Attackers with admin or owner privileges in any organization can retrieve decrypted upstream provider credentials for other tenants, including plaintext OpenAI, Anthropic, and Bedrock API keys.

Craft CMS 5.0.0-RC1 before 5.10.11 GraphQL Entry Mutation Site Scope Bypass
Summary
Craft CMS versions before 5.10.11 contain a site scope bypass vulnerability in GraphQL entry mutation resolvers that fail to validate siteId through ArgumentManager::prepareArguments(). Attackers with tokens scoped to one site can read, modify, or delete entries across unauthorized sites by passing siteId directly in mutation arguments.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
