# Security policy ## Supported versions Fixes are made on the latest release only. | Version | Supported | | -------------- | --------- | | Latest release | Yes | | Older releases | No | ## Reporting a vulnerability Please do not open a public issue for a security problem. Report it privately through GitHub instead: on the repository's **Security** tab, choose **Report a vulnerability**, or go straight to . Helpful details to include: - the image version you tested, - what an attacker could do and under what conditions, - steps to reproduce it, and - a suggested fix, if you have one. Never include a real API token or webhook URL. A made-up one shows the problem just as well. You can expect an acknowledgement within a week. How quickly a fix follows depends on severity; you'll be kept informed, and credited in the release notes unless you'd rather not be. ## Scope Especially worth reporting: - any way the API token or the notification webhook URL could leak: logs, process listings, the environment of child processes, image layers, error messages or the notifications themselves; - any way to make the container write an address that did not come from a validated lookup, or change records it was not configured to manage. Vulnerabilities in Cloudflare's own services should go to Cloudflare. Issues in Alpine packages are fixed by rebuilding the image, but please do report it if a published image lags behind an important update.
