Security at QWED

QWED maintains public remediation guidance for disclosed security issues affecting released packages. When an issue is confirmed, we aim to validate the affected scope, ship a fix, publish version guidance, and preserve a clear record for downstream users and security reviewers.

How QWED handles public security issues

The public disclosure and remediation lifecycle

Report → Validate → Fix → Release → Disclose → Verify

The sequence is designed to make remediation actionable for users while retaining a public evidence trail of the affected version, fix, and source records.

Responsible vulnerability disclosure

Coordinated intake and resolution

QWED welcomes responsible vulnerability reports. Please report potential vulnerabilities privately through the GitHub Security Advisory private reporting flow or contact maintainers directly rather than filing a public issue for an unpatched vulnerability. We will assess the report, coordinate remediation where appropriate, and acknowledge contributors in public disclosures when they consent to credit.

Deployment and verification controls

Architecture principles for production AI safety

Deployment flexibility

Use QWED where your risk model requires it, including managed environments, self-hosted deployments, and tighter internal boundaries.

Data handling controls

Verification workloads often need clear controls around retention, transport, storage, and operational access. QWED is designed with those requirements in mind.

Auditability

The point of a verification layer is not only to block errors, but also to make it clear what was checked, what failed, and why a result was allowed through.
