# Security Policy Kammer is a privacy-first, self-hosted community platform. Security reports are taken seriously and handled with priority. ## Supported versions Until 1.0, only the latest release (and the `main` branch) receive security fixes. ## Reporting a vulnerability **Please do not open a public issue for security vulnerabilities.** Instead, report privately via GitHub Security Advisories ("Report a vulnerability" on the repository's Security tab). Include, where possible: - A description of the vulnerability and its impact - Steps to reproduce (proof of concept welcome) - Affected version/commit and configuration (storage adapter, reverse proxy, …) ## What to expect - **Acknowledgment** within 72 hours. - **Assessment and triage** within 7 days: severity, affected versions, remediation plan. - **Fix and disclosure**: we aim to ship fixes for high-severity issues within 30 days. We coordinate disclosure timing with the reporter and credit reporters in the release notes unless they prefer otherwise. ## Scope notes for self-hosters - The server operator can always technically read the database — this is documented product behavior (see SPEC.md §3), not a vulnerability. "Sealed" groups protect against _community admins_, not against the instance operator. - Reports about missing rate limits, guest-link token weaknesses, upload hardening bypasses (content-type spoofing, SVG payloads, EXIF leakage), and authorization/visibility violations are all firmly in scope and especially welcome.
