enzan is maintained by one person. This document says where to send a vulnerability report, what happens after you do, and what is in scope.
Use GitHub's private vulnerability reporting on this repository — the "Report a vulnerability" button under the Security tab. It opens a private thread visible only to the maintainer, so the report never sits in a public issue while a fix is being written.
Please do not open a public issue for a suspected vulnerability. If private reporting is unavailable to you for any reason, open a public issue that says only that you have a security report and asks for a contact — no details.
What helps most in a report: what an attacker can reach, the steps to reproduce it, and the version or commit you saw it on. A proof of concept is welcome but not required.
This is a single-maintainer project, so these are commitments a single person can keep rather than a team SLA:
| Stage | Target |
|---|---|
| Acknowledge the report | within 7 days |
| Initial assessment — is it a vulnerability, and how severe | within 30 days |
| Fix, or an explanation of why it will not be fixed | discussed with you once assessed |
| Public disclosure | when the fix ships, or 90 days after the report, whichever is first |
The 90-day deadline is the industry norm and it runs regardless of whether a fix is ready, because an unfixed issue that stays secret indefinitely protects nobody but the project. If you need it held longer — a coordinated release with another project, for example — say so and it can be agreed.
Reports are handled through GitHub security advisories, which means you are credited on the published advisory unless you ask not to be. There is no bug bounty; nothing here is offered in exchange for a report.
In scope: behaviour of enzan itself that lets input it does not control reach memory, resources, or data it should not — including a panic the API does not document — and a dependency with a known vulnerability that enzan actually exercises.
Out of scope: anything that assumes the attacker already controls the application embedding enzan, and bugs in third-party software — report those upstream.
Good-faith research on your own installation is welcome and will not be met with legal action. "Good faith" means: your own data, no third party's, no attempt to reach anyone else's machine, and no public disclosure before the window above closes.
If a report shows that protected content is already published — a credential in history, personal data in a fixture — it stops being a vulnerability report and follows After a disclosure, which is where the containment and notification steps live.
