Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: A vulnerability in the 'ws' dependency (CVE-2026-48779) could allow remote attackers to cause memory exhaustion and crash the sandbox process via malicious WebSocket frames. Developers must ensure WebSocket libraries are locked to safe versions.

Incomplete Hostname/Content-Type Verification: The api-client component failed to verify the response Content-Type during file read operations, allowing arbitrary error payloads or HTML to be piped directly into local destination file streams.
