CVE-2026-101028

Ash.count, Ash.exists and Ash.aggregate skip related resources' read policies in filters and sorts

Published Oct 9, 2026 · corrected/updated Oct 9, 2026 · evidence confidence high

## Summary Incorrect Authorization vulnerability in ash-project ash allows an actor to infer data in related records they cannot read via , and . ( ) applied only the root resource's read policy before running the aggregate query. The read path also applies each related resource's read policy to filter and sort references that cross a relationship, directly (for example ) or through an aggregate over one, but the aggregate path skipped that step. A caller whose filter or sort reaches these functions, for example through , an ash_lua script, or an AshAi tool offering count or exists results, can test conditions against related rows hidden from them and recover their existence and attribute values one query at a time. and its page counts are not affected. This issue affects ash: from 2.6.0 before 3.34.6. ## Configurations Reachable only when an application passes caller-supplied filters or sorts that cross a relationship into , or (directly, through ash_lua read operations, or through AshAi count, exists or aggregate result types), and a related resource's read policy is stricter than the root resource's.
