hunting-blind-and-second-order-sql-injection skillA

hunting-blind-and-second-order-sql-injection is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt the SQL injection that first-order testing misses: blind injection where the response carries no error or data and the signal is a boolean difference or a timing delay, and second-order injection where input is stored safely on one request and later concatenated into a query on a different code path. Covers values that reach a query only after being read back from the database, a cache, or a log, and sinks that reveal nothing directly so confirmation depends on an inferential channel. Use w.

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-blind-and-second-order-sql-injection@git:20260826.c45369b
Exact content
mdr add unboundcompute/security-agent-skills/hunting-blind-and-second-order-sql-injection@sha256:84ad4239a1f84667

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.
