Security policy

OpenCheckpoint is a specification. Security issues include:

  • Flaws in the specification or schema that let a conforming consumer be manipulated into an unsafe action: authority transfer, prompt injection that the statement model fails to contain, replay of side effects, or acceptance of forged approvals.
  • Gaps in the threat model.
  • Vulnerabilities in the repository’s tooling, documentation site, or any SDK published from this repository.

Report a vulnerability in a third-party product that implements OpenCheckpoint to that product’s maintainers.

Report vulnerabilities privately through GitHub’s private vulnerability reporting on this repository (Security → Report a vulnerability). Do not open a public issue.

Include what is affected (section, schema path, or file), how it can be exploited, and, if possible, a fixture that demonstrates it.

Maintainers acknowledge reports within five business days, agree on a disclosure timeline with the reporter (normally no more than 90 days), and credit the reporter unless asked not to. Maintainers fix a specification flaw in a new version and publish the change and its rationale in the changelog and the threat model.

Only the latest published specification version and the main branch receive fixes during the 0.x series.
