Detailsinfo

A vulnerability was found in ash-project ash_sql up to 0.7.0. It has been rated as problematic. This issue affects the function AshSql.Aggregate.different_queries?. The manipulation with an unknown input leads to a improper authorization vulnerability. Using CWE to declare the problem leads to CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. Impacted is confidentiality. The summary by CVE is:

Incorrect Authorization vulnerability in ash-project ash_sql allows a caller to receive an aggregate value computed over rows a more restrictive filter should have excluded, disclosing counts, sums, or lists across an authorization or tenancy boundary. AshSql.Aggregate.different_queries?/2 reports two aggregate queries as different only when their filter and their sort both differ. Aggregate queries rarely carry a sort, so two aggregates that share a name but carry entirely different filters compare as identical. The colliding aggregate keeps its name and is treated as already computed, and select_aggregates returns the first-registered variant's value. The same name reaches the builder twice with different filters when actor or tenant context is stamped into each aggregate's query, so a narrowly filtered aggregate can be served the value of a previously registered broad one. This issue affects ash_sql: from 0.1.0 before 0.7.1.
