auditing-websocket-connection-trust skillA

auditing-websocket-connection-trust is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit a WebSocket endpoint for trust established once at the handshake and never re-checked, so a cross-site page or a post-handshake message drives a privileged action, after the origin check and the credential source are resolved. Covers a missing or always-true origin check on the upgrade with ambient-cookie authentication, authentication at the handshake with no per-message authorization, a message treated as transport into a downstream injection sink, an unbounded frame or connection allowa.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/auditing-websocket-connection-trust@git:20260825.70f8609
Exact content
mdr add unboundcompute/security-agent-skills/auditing-websocket-connection-trust@sha256:ddcf55a5c6a109b3

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
