What is the CVSS score of CVE-2026-29194?

CVE-2026-29194 has a CVSS 3.1 base score of 8.1 (High). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N. EPSS exploitation probability: 0.1%.

How to fix or mitigate CVE-2026-29194?

Within 24 hours: Identify all Netmaker deployments and document current versions; isolate or restrict network access to affected instances if version < 1.5.0 is confirmed. Within 7 days: Upgrade to Netmaker version 1.5.0 or later; if upgrade is not immediately feasible, implement network segmentation to limit exposure and enable enhanced logging on Netmaker API endpoints. Within 30 days: Conduct security audit of network access logs for unauthorized JWT token usage; perform penetration testing on upgraded instances to validate remediation.

AnalysisAIv1 – Mar 12, 2026

Netmaker versions prior to 1.5.0 fail to properly validate host JWT tokens during authorization, allowing any attacker with knowledge of target object identifiers to bypass access controls and read, modify, or delete resources across different hosts. The vulnerability affects critical operations including node management, host deletion, and failover configurations, requiring only a valid host token and network access to exploit. Update to version 1.5.0 or later to remediate.

Classified as CWE-863 (Incorrect Authorization). Affects Netmaker. Netmaker makes networks with WireGuard. Prior to version 1.5.0, the Authorize middleware in Netmaker incorrectly validates host JWT tokens. When a route permits host authentication (hostAllowed=true), a valid host token bypasses all subsequent authorization checks without verifying that the host is authorized to access the specific requested resource. Any entity possessing knowledge of object identifiers (node IDs, host IDs) can craft a request with an arbitrary valid host token to access, modif

DescriptionGitHub Advisory

Netmaker makes networks with WireGuard. Prior to version 1.5.0, the Authorize middleware in Netmaker incorrectly validates host JWT tokens. When a route permits host authentication (hostAllowed=true), a valid host token bypasses all subsequent authorization checks without verifying that the host is authorized to access the specific requested resource. Any entity possessing knowledge of object identifiers (node IDs, host IDs) can craft a request with an arbitrary valid host token to access, modify, or delete resources belonging to other hosts. Affected endpoints include node info retrieval, host deletion, MQTT signal transmission, fallback host updates, and failover operations. This issue has been patched in version 1.5.0.

Executive ViewAI

Why It Matters

Netmaker versions prior to 1.5.0 contain a critical authentication bypass vulnerability in JWT token validation that could allow unauthorized access to network infrastructure. Organizations running affected versions face immediate risk of unauthorized network access and potential lateral movement by attackers, requiring urgent assessment and mitigation.

Business Impact: High

Compensating Controls

Implement network segmentation to restrict Netmaker API access to trusted administrative networks only; enable request rate limiting and IP allowlisting on Netmaker endpoints; deploy WAF rules to detect and block malformed or invalid JWT token patterns in Authorization headers; require multi-factor authentication for all administrative access; increase monitoring and alerting on failed authentication attempts and token validation errors; disable remote access to Netmaker management interfaces if not actively required.
