MEDIUMPre-NVD 6.06.0
EchelonGraph scoreLOW confidence

This medium-severity CVE scores 6.0 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Incorrect Authorization vulnerability in ash-project ash allows an actor to infer data in related records they cannot read via Ash.count/2, Ash.exists/2 and Ash.aggregate/3.

Ash.Actions.Aggregate.run/4 (lib/ash/actions/aggregate.ex) 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 comments.body) 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 Ash.Query.filter_input/2, 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. Ash.read/2 and its page counts are not affected.

This issue affects ash: from 2.6.0 before 3.34.6.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
