PreviewShield is a community-maintained open-source project. Support is best-effort and does not include an uptime or response-time guarantee.
- Read the getting-started guide and policy reference.
- Run
previewshield --versionand reproduce with the latest supported release. - Run
previewshield policy validate PATHwhen configuration is involved. - Search existing issues for the exact error or rule ID.
- Remove credentials, internal hostnames, private addresses, and sensitive response data from anything you plan to post publicly.
- Reproducible defects belong in a bug report.
- Product proposals belong in a feature request.
- Security vulnerabilities must follow SECURITY.md and must not be posted publicly.
Include the version, operating system, Python version, redacted command, policy, expected result, actual result, and smallest safe reproduction. Maintainers may close requests that cannot be reproduced or that concern an unsupported version.
The issue tracker is not a security consulting service and cannot determine whether a third-party website is vulnerable. PreviewShield findings are hardening signals; remediation must be reviewed in the application's own architecture and threat model.
Commercial support and private remediation guidance are not currently offered.
