**Preferred channel:** [security@szlholdings.com](mailto:security@szlholdings.com)

**Alternate channel:** [Open a private security advisory](https://github.com/szl-holdings/.github/security/advisories/new) on GitHub.

**Alternate email:** [stephen@szlholdings.com](mailto:stephen@szlholdings.com)

**PGP / encrypted comms:** Optional — if you require encrypted communication, request the maintainer's public key at [security@szlholdings.com](mailto:security@szlholdings.com). Key fingerprint available on request.

**Response SLA:** We acknowledge all vulnerability reports within **48 hours**.

- A clear description of the issue and its potential impact.
- Steps to reproduce, including any proof-of-concept code, requests, or payloads.
- The affected version, commit SHA, or environment.
