Exploiting ORM injection (ORM Leak) where applications pass attacker-controlled keys/operators directly into ORM query builders (Django, Prisma, Beego, Ransack, Entity Framework/OData), letting attackers smuggle relational filters and comparison operators to leak hidden columns (passwords, reset tokens, TOTP secrets) via boolean, error, or timing oracles, and to bypass field deny-lists. Activates when request data is spread into filter/where clauses.

# Exploiting ORM Injection (ORM Leak)
## When to Use
- During authorized tests where an endpoint spreads request JSON/query params into an ORM filter
- When you see Django `filter(**request.data)`, Prisma `findMany(req.body)`, Beego `QuerySeter.Filter()`, Ransack `Model.ransack(params[:q])`, or OData `$filter`
- When search/list endpoints accept structured filters, bracket syntax (`field[op]=v`), or `field__operator` keys
- When auth flows compare secrets (reset tokens, API keys, magic links) with attacker JSON that may carry operator objects
- When you need to leak columns not meant to be exposed, by pivoting through model relations
## Critical: Variants Most Often Missed
The miss is treating these as "just a search filter." Attacker-controlled keys let you traverse relations and inject operators to build a leak oracle. Test per framework:
