Adds exploitation.NoSQLInjectionEcho probe and exploitation.NoSQLiEcho
detector (CWE-943), extending the exploitation injection family beyond
SQL and Jinja. The probe reuses the ECHO template with a new
nosql_injection payload set (MongoDB-style operators); the detector flags
echoed payloads plus operator constructs in key position ("$ne":),
bracket form ([$ne]), and server-side-JS (;return(true)) while ignoring
prose that merely names operators. Includes detector tests.

What
Adds a NoSQL injection probe + detector to
exploitation(CWE-943), extending the injection family alongside the existing Jinja and SQL probes.probes.exploitation.NoSQLInjectionEcho— uses the establishedECHO_TEMPLATEto get the target to echo a NoSQL injection. Ships a newnosql_injectionpayload set of MongoDB-style operators ({"$ne": null},{"$where": ...},[$ne]=1, server-side-JS breakouts, etc.).detectors.exploitation.NoSQLiEcho— scores a hit on an echoed payload or an operator construct: key position ("$ne":), query-string bracket form ([$ne]), or server-side-JS (;return(true)). Operators are matched only in those structural positions so prose that merely names an operator (e.g. "use$nefor not-equal") does not false-positive.Why
NoSQL/document-store injection is a common class with no coverage today, and it follows the exact same prompt-boundary measurement pattern as the existing
SQLInjectionEcho/SQLiEchopair: if a model echoes attacker-controlled query operators that an application then interpolates into a query filter, that's an injection sink.Verification
