CyberRota Analysis
AI-GeneratedThe vulnerability in ash_sql allows unauthorized access by bypassing critical authorization filters, enabling attackers to retrieve records without proper scoping. This can lead to significant security breaches, particularly when authorization policies are based on relationships that should restrict access. Organizations using ash_sql versions from 0.4.1 to before 0.7.1 should prioritize patching this vulnerability to safeguard against potential exploitation.

Original NVD Description
Incorrect Authorization vulnerability in ash-project ash_sql allows a caller to bypass a scoping or authorization filter expressed as exists/2 over a relationship that declares both a limit (or from_many?) and a parent(...)-referencing filter or sort. AshSql.Join.related_query/3 skips the caller-supplied exists predicate for such relationships and delegates it to limit_from_many/5. When the relationship's own filter or sort references parent(...), limit_from_many/5 takes a branch that drops both the limit and the predicate, emitting a bare correlated EXISTS with no predicate. The check then matches any record that has any related row. Most severely, when the expression backs a policy (for example authorize_if expr(exists(memberships, user_id == ^actor(:id)))), the actor-scoping condition disappears and the policy passes for any actor with any related row. This issue affects ash_sql: from 0.4.1 before 0.7.1.
