Audit client code for transport security that is disabled or defeated, so an attacker on the network path can intercept a connection the client believes is protected. Covers verification switched off (a trust-all setting, a permissive flag, an environment override), a custom trust manager or callback that returns success unconditionally, a hostname check that is skipped or always passes, acceptance of an expired or self-signed certificate through a swallowed error, certificate pinning that is…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Auditing TLS and certificate validation: when the client accepts a certificate it should reject Transport security fails closed by default, so almost every real finding here is code that went out of its way to weaken it. A client that turns verification off, installs a trust manager that approves any chain, skips the hostname check, or swallows an expired-certificate error will complete a handshake against an attacker's certificate and hand plaintext to whoever sits on the network path. This is not about which cipher or protocol version is chosen, that is a different audit; it is about whether the client accepts a certificate it should have rejected. You audit it by finding every outbound TLS client and asking, for each, whether verification, hostname matching, and any required pinning are enforced and fail closed on the reachable production path. The discipline is separating a genuine production bypass from a test-only flag pointed at localhost. ## When to use - Code opens an outbound TLS connection, or configures an HTTP, gRPC, database, or raw socket client. - You see a verification flag, a custom trust manager, a hostname verifier, or a pinning routine. …

How to install
mdr add unboundcompute/security-agent-skills/auditing-tls-and-certificate-validation@sha256:8e663707f4f726c7The line at the top of this page pins the label git:20260823.e797ed0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
