We prefer transparency: if you find a security problem in pyhaul, you are welcome to open a pull request (or a public issue if a PR is not practical) so the fix and any discussion can happen in the open.

If you need private coordination first—for example, you believe disclosure should wait until a patch is ready—use GitHub’s security advisory flow:

https://github.com/chad-loder/pyhaul/security/advisories/new

In either case, we aim to acknowledge reports within 72 hours.

Security fixes land in the current and previous minor releases of the latest major version.

In scope:

• Remote code execution via crafted HTTP responses or redirects.
• Path traversal or arbitrary file writes via Content-Disposition or URL-derived filenames.
• Memory exhaustion via hostile servers (unbounded Content-Length, pathological compression ratios, etc.).
• TLS downgrade, certificate validation bypass, or hostname confusion.

Out of scope:

• Issues in dependencies (report to httpx, niquests, etc. directly).
• Attacks that require local filesystem access or a compromised host.
• Self-DoS from passing absurd inputs to the API.
