CVE-2026-114214 · Severity: info · Published 2026-10-25

Ash is a data framework for building Elixir applications. A flaw in how the framework loads related records allows an authenticated client to enumerate and read records they shouldn't have access to by paging through relationships. An attacker can systematically retrieve sensitive data from the destination resource that would normally be protected by access policies.

## How to fix

- Fixed in 3.37.1

## Technical details

An incorrect authorization vulnerability in ash's lateral_join?/4 function (lib/ash/actions/read/relationships.ex) fails to apply source-to-destination filters when loading has_many through relationships with limit: 1 or unsorted has_one through relationships with limit: 1. The destination policies still run with the relationship context (accessing_from), but because the join filter is omitted, an attacker can page through records using offset/limit to enumerate all records the policy permits in that context.

## Affected products
