testing-web-cache-attacks skillA

testing-web-cache-attacks is agent-read markdown (skill) from unboundcompute/security-agent-skills: Test how a caching layer between users and an application can be turned against it: cache poisoning (getting a harmful response stored and served to other users) and cache deception (tricking the cache into storing a victim's private response where the attacker can read it). Covers finding the cache key and unkeyed inputs, identifying cacheable responses, poisoning through unkeyed headers, and deceiving path-based caching into storing authenticated content. Use when reviewing a CDN, a reverse pr.

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/testing-web-cache-attacks@git:20260816.a0bc1d1
Exact content
mdr add unboundcompute/security-agent-skills/testing-web-cache-attacks@sha256:17b8c9b8c4ff8889

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.
