CVE-2026-85178
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
