# Security Policy Hermes Secure Email Gateway is a security product, and we take vulnerabilities in it seriously. Thank you for helping keep Hermes and its users safe. ## Supported versions Hermes uses calendar versioning (`vYYMMDD`). Security fixes are issued against the **most recent published release**. Older releases are not maintained — if you are running an older version, upgrade to the latest before reporting, where practical. | Version | Supported | | --- | :---: | | Latest published [release](https://github.com/deeztek/Hermes-Secure-Email-Gateway/releases) | ✅ | | Any older release | ❌ (upgrade first) | ## Reporting a vulnerability **Please do _not_ open a public GitHub issue for security vulnerabilities.** Public issues are visible to everyone, including potential attackers, before a fix is available. Instead, report privately through either channel: - **GitHub private vulnerability reporting** (preferred): use the **"Report a vulnerability"** button under this repository's **Security** tab. This opens a private advisory visible only to the maintainers. - **Email:** with a subject line beginning `SECURITY:`. Please include, where you can: - A description of the vulnerability and its impact. - The affected version(s) and component/container. - Step-by-step reproduction (proof-of-concept if available). - Any suggested remediation. ## What to expect - **Acknowledgement** of your report, typically within **3 business days**. - An assessment and, for confirmed issues, a remediation plan with a target timeline. - **Coordinated disclosure:** we will work with you on timing and will credit you in the release notes / advisory unless you prefer to remain anonymous. ## Scope This policy covers the Hermes Secure Email Gateway code in this repository. Bundled third-party components (e.g. Postfix, Dovecot, Amavis, ClamAV, Lucee, Nextcloud, Authelia) should be reported to their respective upstream projects; if a Hermes default configuration exposes such a component insecurely, that **is** in scope. ## Non-vulnerability bugs For ordinary bugs and feature requests (no security impact), please use [GitHub Issues](https://github.com/deeztek/Hermes-Secure-Email-Gateway/issues).
