ash is vulnerable to Uncontrolled Resource Consumption
59
Medium Risk
This Affects:
ashTL;DR
The runtime filter evaluator flattens records across relationship paths, producing an unbounded cartesian product when a filter spans multiple to-many relationships. The intermediate list is fully materialized with no bound on related data. A crafted filter can exhaust memory and CPU, causing denial of service. The fix streams relationship flattening so memory stays bounded.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you evaluate filters that span multiple to-many relationships in the runtime evaluator.
Background info
ash is vulnerable to Uncontrolled Resource Consumption in versions 1.30.0 - 3.32.1.
How to fix this
Upgrade the ash library to the patch version.
