| Título | a2aproject a2a-go ≤ v2.4.0 CWE-209 |
|---|
| Descrição | a2aproject a2a-go up to v2.4.0 discloses push notification credentials in error responses. In a2asrv/agentexec.go, CreateExecutor formats a failed push config store write with %v on params.Config.PushConfig, embedding the whole structure in the error message that is returned to the client in the JSON-RPC/REST error payload. This exposes the webhook token plus authentication.scheme and authentication.credentials, which are write-only by design and not returned by any other API operation. Triggering a store failure makes the caller receive those secrets, enabling unauthorized push delivery to an attacker endpoint or impersonation of the agent toward the webhook. CWE-209/CWE-200, fixed in v2.5.0 (PR #393). |
