hunting-broken-object-level-authorization skillA

hunting-broken-object-level-authorization is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt broken object-level authorization (BOLA, also called IDOR): endpoints that accept a client-supplied object reference - a numeric id, UUID, key, slug, filename, or an id nested in a request body or token - and read or mutate that object without checking the authenticated caller is entitled to it. Covers direct references, enumerable and guessable ids, references buried in nested or batch payloads, second-order ids stored then trusted later, and ownership checks that run on one path but not i.

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

mdr add unboundcompute/security-agent-skills/hunting-broken-object-level-authorization@git:20260819.0218064
Exact content
mdr add unboundcompute/security-agent-skills/hunting-broken-object-level-authorization@sha256:2730c13ba96476a4

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.
