Description

This security bulletin contains information about 1 vulnerability.


1) Improper access control (CVE-ID: N/A)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote user to access owner-only MCP tools and disclose sensitive information.

The vulnerability exists due to improper access control in the hook ingress and bundled CLI backend selection when starting a hook-triggered automated agent run through the /hooks/agent endpoint with a valid hook token. A remote user can trigger a hook-initiated run that selects a bundled CLI backend to access owner-only MCP tools and disclose sensitive information.

Only deployments with hooks enabled are vulnerable.
