Sources and claim methodology

Upstream source description

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.
