Security Policy

Supported versions

Security fixes are made against the latest KyPost release. Upgrade to the current release before reporting a problem that may already have been fixed.

Report vulnerabilities privately through GitHub Security Advisories. Do not open a public issue containing vulnerability details.

Include the affected version, impact, reproduction steps, and any suggested mitigation. Reports are acknowledged within two business days. Disclosure and credit are coordinated with the reporter after a tested fix is available.
