CVE-2026-108549 · Severity: high · CVSS 8.1 · Published 2026-10-10

cc-connect is a bridge that connects local AI coding agents to messaging platforms. When webhook mode is enabled for the MAX platform adapter without a secret configured, the application fails to validate incoming webhook requests. An attacker on the network can send forged updates to the webhook listener to impersonate admin users and execute arbitrary shell commands on the host.

## Technical details

The MAX platform adapter in platform/max/max.go accepts unauthenticated webhook updates when no webhook_secret is configured, failing to verify the origin of incoming requests. An attacker with network access to port 8080 can forge webhook payloads containing an allowed or admin user_id and invoke privileged operations like /shell commands. This is a missing authentication vulnerability that requires network access to the webhook endpoint but no prior authentication.
