CyberRota Analysis

AI-Generated

The vulnerability affects the AI Bridge Proxy in Coder versions 2.30.0 through 2.32.6, which defaults to accepting any TLS certificate for outbound HTTPS connections when no upstream proxy is configured, potentially allowing man-in-the-middle attacks. Organizations using these versions should prioritize remediation to prevent unauthorized access to sensitive data, particularly those with network configurations that could expose the AI Bridge Proxy to untrusted environments. Upgrading to versions 2.32.7, 2.33.8, or 2.34.2 is essential to enforce secure transport unconditionally.

Original NVD Description

Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.30.0 and prior to versions 2.32.7, 2.33.8, and 2.34.2, the AI Bridge Proxy (`aibridgeproxyd`) created a goproxy server whose default transport set `InsecureSkipVerify: true` and only assigned a secure transport when an upstream proxy was configured. In the default configuration (no upstream proxy), outbound HTTPS to the Coder access URL accepted any TLS certificate. Practical exploitation requires an on-path (man-in-the-middle) position between the AI Bridge Proxy and the Coder server. Deployments where they are co-located over loopback are effectively unaffected. The fix in versions 2.32.7, 2.33.8, and 2.34.2 applies the secure transport (TLS 1.2 or higher using system root CAs) unconditionally. As a workaround, ensure the Coder access URL uses a trusted certificate and secure the network path between the AI Bridge Proxy and the Coder server (for example, loopback or mTLS).
