CVE-2026-7234Public exploitNetwork attack vector

Unauthenticated file disclosure via unsanitized request paths

Published Apr 28, 2026 · Updated Apr 28, 2026

Path traversal in Browser Operator Core 0.6.0 and earlier allows remote attackers to read files through crafted component-server URLs. scripts/component_server/server.js derives filesystem paths from request.url without sanitizing traversal components, while traces mode uses a separator-blind startsWith boundary check. The component server must be running and reachable, and exposure is limited to files readable by its process within or adjacent to generated output roots.
