Security policy

WardenClaw is an execution gate: a way around the gate is the most important bug you can find. Thank you for reporting it privately.

How to report

Please do not open a public issue, discussion or pull request for a vulnerability.

Write to valiullin.arthur@gmail.com. GitHub private vulnerability reporting is not turned on for this repository yet.

Please include what you found, the affected version or commit, how to reproduce it and the impact you expect. A proof of concept helps a lot.

Encryption

There is no PGP key for reports yet. By email, send the description and the impact first, without a working exploit, and we agree on a private way to pass the details.

Response times

• An acknowledgement within 7 days.
• An assessment and a plan within 30 days.
• Coordinated disclosure: we publish a fix and an advisory and credit you, unless you prefer otherwise. We ask for up to 90 days before public disclosure; tell us if you need a different timeline.

WardenClaw is pre-1.0. Security fixes go to the main branch and the latest release only.

Scope

In scope:

• forging, replaying or redirecting an approval: ticket or envelope signature bypass, digest confusion, canonical JSON divergence between implementations, nonce or time window bypass, pairing takeover;
• getting a command executed without a valid approval (for wardend: seccomp filter escape, TOCTOU between approval and execution, exec paths that are not gated);
• tampering with the hash-chained journal without detection;
• leaking device or supervisor keys.

Out of scope:

• attacks that need root on the gated machine, or control of the phone’s OS;
• the known limits of the single-user (same-uid) installation described in Why the model can’t turn it off: use the hardened install for a real security boundary;
• denial of service by the operator’s own agent (it can always stop working);
• vulnerabilities in third-party dependencies with no WardenClaw-specific impact: report them upstream, and tell us if WardenClaw needs to react.

Release integrity

Releases are not signed. The installer checks the archive against the release’s checksums.txt, both from GitHub over TLS, and nothing more; how to check the installer yourself before piping it into sudo: Install wardend.
