CVE-2026-115627: ash-project ash_postgres incorrect authorization in many-to-many relationships

CVE-2026-115627 · Severity: info · Published 2026-10-25

ash_postgres is a database layer for the Ash framework that manages data access and relationships.

Technical details

An incorrect authorization flaw in ash_postgres's lateral join handling (lateral_join_query/3 and through_step_queries/4) skips attribute-based multitenancy checks on intermediate resources in join paths. When relationships are loaded with lateral joins (per-record limit or sort), rows from other tenants are incorrectly joined, exposing destination records to unauthorized callers.
