orm-filter-data-leak from dreadnode/capabilities is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Exploit ORM search/filter endpoints to leak data from joined/related tables via relationship traversal operators. Use when search, filter, or list endpoints are backed by an ORM (Django, Rails, Laravel, Sequelize, Hibernate).
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
# ORM Filter Data Leak ## Pattern - Search/filter endpoints accepting field names or operators as parameters - ORM-style syntax visible: double underscores `__`, dot notation, nested objects - Response length or timing varies with different filter values - Verbose errors revealing model/field names ## Probe Traverse relationships to access fields from joined models: ``` GET /api/users?email__contains=a GET /api/users?profile__ssn__startswith=1 GET /api/users?created_by__password__contains=a GET /api/search?q[password_digest][startswith]=abc ``` Operators to try: `__contains`, `__startswith`, `__gt`, `__lt`, `__exact`, `__icontains`. Chain through relations: `model__related_model__field__operator`. Alternative syntax: `field[operator]=value`, `field.operator=value`. Use boolean oracle (result count changes) or timing (collation-based `__gt`/`__lt`) to extract character-by-character. ## Indicators - Response size changes reveal boolean oracle (matching vs non-matching records) - Result count differs when filtering on fields that shouldn't be exposed - Errors reveal ORM field names or relationship paths ## Chain With …

How to install
mdr add dreadnode/capabilities/orm-filter-data-leak@sha256:c5c33b004529783eThe line at the top of this page pins the label git:20260504.2a64374, 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.
