CVE-2026-92717: Missing Authentication for Critical Function in cobbr Covenant
CVE-2026-92717 is a critical vulnerability in Covenant through version 0.6 where the CovenantHub SignalR hub lacks authentication. This allows unauthenticated users to invoke the CreateHttpListener function and obtain a signed JWT token. With this token, attackers can authenticate to the operator API and access sensitive resources such as grunts, credentials, binaries, events, and the operator roster.
AI Analysis
Technical Summary
CVE-2026-92717 describes a missing authentication control in the CovenantHub SignalR hub in Covenant versions up to 0.6. The hub is registered without an Authorize attribute, enabling unauthenticated callers to invoke CreateHttpListener and receive a signed JWT token. This token grants access to the operator API, allowing attackers to interact with critical components including grunts, credentials, binaries, events, and the operator roster, effectively compromising the operator's control environment.
Potential Impact
An attacker can gain unauthorized access to the operator API by obtaining a signed JWT token without authentication. This access allows them to view and manipulate sensitive operational data and resources, including grunts, credentials, binaries, events, and the operator roster, which can lead to full compromise of the operator environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the CovenantHub SignalR hub and monitor for unauthorized usage. Applying an Authorize attribute to the hub registration to enforce authentication is necessary to mitigate this vulnerability.
