Use GitHub's private Report a vulnerability form. Include the affected Sink version or commit, reproduction steps, impact, and relevant deployment settings with credentials and private data removed. Please keep exploit details out of public issues while a report is being investigated.
Use the latest release when checking whether an issue is still present. Older releases do not have a guaranteed security backport schedule. Report suspected vulnerabilities even if you cannot reproduce them on the latest release.
Review the configuration reference and reliability guide for dependency access, resource limits, health checks, and durability settings. The Docker Compose quickstart is a local development environment.
