Bluehood monitors local bluetooth activity. Prior to version 0.7.1, when auth_enabled is set in Bluehood, only the HTML page handlers enforced session validation. The /api/* handlers (settings, devices, groups, per-device endpoints including /api/device/{mac}/notes) called no auth check at all. A network attacker reachable on the dashboard port could read Bluetooth tracking data and modify application state - including the heartbeat URL, prune retention, device groups, and per-device notes - without a session cookie. This issue has been patched in version 0.7.1.

AnalysisAI
Unauthenticated access to Bluehood's /api/* endpoints in releases before 0.7.1 lets any network attacker who can reach the dashboard HTTP port read Bluetooth tracking data and rewrite application state - the heartbeat URL, prune retention, device groups and per-device notes - whenever the operator has enabled the opt-in auth_enabled setting. The root cause is a missing authorization check: only the HTML page handlers called the session-validation routine, while the settings, devices, groups and /api/device/{mac}/notes handlers performed no check at all, allowing requests carrying no session cookie to succeed (CWE-306, CVSS 3.1 9.1 with PR:N/AC:L). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the operator has enabled the opt-in `auth_enabled` setting (the flaw is the failure to enforce that intended authentication) AND that the attacker has network reachability to the Bluehood dashboard HTTP port; no session cookie, credentials, or user interaction are needed once the port is reachable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All signals converge on a genuine access-control failure, but real-world urgency is tempered by product footprint. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Bluehood 0.7.1, the vendor-released patch, which adds a default-deny authentication middleware and version-tagged release (GHSA-qj2j-wcg3-74jw, commit 401479938c0deb1f6f6847d442f98a2d03efca68, tag v0.7.1); no partial in-place configuration change restores the intended session enforcement in earlier builds. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Bluehood instances running versions before 0.7.1 and immediately restrict network access to the dashboard HTTP port to trusted hosts only, preferably binding to localhost or placing behind a VPN. …
