Do not open a public issue for a security problem.
Report it privately through GitHub: Report a vulnerability. That opens a private advisory only the maintainers can see.
If you cannot use GitHub advisories, email ronny@no42.org.
Expect an acknowledgement within a few days. Please give us a reasonable window to ship a fix before disclosing publicly; we will credit you in the advisory unless you would rather we didn't.
This repository is the Helm chart. Chart-side issues are in scope:
insecure defaults in values.yaml, privilege or RBAC problems in the
rendered manifests, secret handling, and the release pipeline itself.
Vulnerabilities in the blittermib application or its container image belong in no42-org/blittermib.
Only the latest published chart version is supported. Published versions are immutable — fixes ship as a new version, never as a retag.
Every published chart is cosign-signed and carries SLSA build provenance. Verify before deploying — commands are in the README and RELEASING.md.
