Hunt injection that survives an object-relational mapper or query builder: untrusted input reaching a raw-query escape hatch, an unparameterizable identifier (a column, table, or sort order), or a structured filter or update object whose keys become query operators or column references. Covers raw-query methods that take a string or fragment, sort and column selectors taken from the request, and operator injection where a request body passed as a filter turns a comparison always-true or…
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
# Hunting ORM and query-builder injection: when the abstraction is not the safeguard Teams reach for an object-relational mapper or a query builder partly to avoid injection, then assume the abstraction handles it. It handles values: a bound parameter is safe no matter what it contains. It does not handle structure. The moment untrusted input becomes a column name, a sort direction, a raw fragment, or an operator inside a filter object, the placeholder machinery is bypassed and the query means something the developer did not write. Classic string-concatenation injection is largely gone from ORM codebases; the live risk moved to the escape hatches and the structured inputs. You find it by separating the calls that bind values from the calls that accept structure and tracing untrusted input into the latter. ## When to use - Data access goes through an object-relational mapper or query builder, not hand-written statements. - Untrusted input reaches a raw-query method, a column, table, or sort argument, or a filter object. - Request bodies are passed as filter or update objects into the data layer. ## Scope check …

How to install
mdr add unboundcompute/security-agent-skills/hunting-orm-and-query-builder-injection@sha256:357228a2e61d1d16The line at the top of this page pins the label git:20260821.4f2a732, 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.
