Please report security vulnerabilities privately. Do not open a public issue for a suspected vulnerability.
Email opensource@simtabi.com with the affected version, a description and impact, and steps to reproduce. You can also use GitHub's private security advisory flow.
We aim to acknowledge within three business days and to provide a remediation timeline after triage. Please allow a reasonable window to release a fix before public disclosure.
simtabi/sis-sdk is a security-first identifier engine. Taken seriously:
- Forging a valid check character, or a defect that lets a malformed identifier verify.
- A grammar/parse defect that accepts an out-of-spec identifier or rejects a conformant one.
- A profile-configuration path that silently weakens the ISO 7064 check or the lifecycle guarantees.
While pre-1.0, only the latest 0.1.x tag is supported. Fixes land on the current tag.
