hunting-server-side-and-edge-side-includes skillA

hunting-server-side-and-edge-side-includes is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt server-side include and edge-side include injection, where untrusted input is reflected into a document that a processor later interprets for include and exec directives. When an origin server has server-side includes enabled, a reflected directive can read a server file or run a command. When a cache, content-delivery network, or proxy in front of the origin parses edge-side include tags, a reflected tag can fetch an internal URL for server-side request forgery, poison a shared cache, or c.

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/hunting-server-side-and-edge-side-includes@git:20260903.6dac719
Exact content
mdr add unboundcompute/security-agent-skills/hunting-server-side-and-edge-side-includes@sha256:802c1d988ca12f63

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.
