Reporting a Vulnerability

Please do NOT open public GitHub issues for security vulnerabilities.

Use one of these private channels:

  1. GitHub Security Advisories (preferred) — open a private advisory at https://github.com/yolo-labz/chrome-bridge/security/advisories/new
  2. Email — contact the maintainer directly via the email listed on https://github.com/phsb5321

What to include

  • Affected version (commit SHA or release tag)
  • Reproduction steps or proof-of-concept
  • Impact assessment (what data/system is at risk)
  • Suggested mitigation (optional)

Response SLA

  • Acknowledgement: within 72 hours
  • Triage + initial assessment: within 7 days
  • Fix or mitigation: target 30 days for high/critical, 90 days for medium/low

We will credit reporters in the release notes unless anonymity is requested.

Verifying Releases

Every release is published with cryptographic provenance via Sigstore. Verify a downloaded release artifact:

gh attestation verify <artifact> --repo yolo-labz/chrome-bridge

SBOMs (CycloneDX 1.7 + SPDX 2.3) are attached to each GitHub Release for supply-chain auditing.

Threat Model

chrome-bridge runs a localhost-only HTTP relay (default 127.0.0.1:9224) that brokers between a Chrome extension and a CLI on the same machine. It does not expose any network surface. The relay trusts any process on the local host that can bind/connect to the loopback interface.

Out-of-scope for this project:

  • Network-level isolation (use OS firewall / namespaces)
  • Multi-user host hardening (single-user dev workstation assumption)
  • Browser fingerprinting resistance
