Description
cc-connect through 1.5.0 contains a missing authentication vulnerability in the MAX platform adapter webhook mode in platform/max/max.go that accepts unauthenticated updates when no webhook_secret is configured. Remote attackers reaching the webhook listener on port 8080 can forge updates with an allowed or admin user_id to run privileged commands like /shell on the host.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-108549 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
