Restricted aggregate disclosure via filter collision
Published Aug 30, 2026 · Updated Aug 30, 2026
Incorrect authorization in Ash Framework AshSql 0.1.0 through 0.7.0 allows attackers to read restricted aggregate values. AshSql.Aggregate.different_queries?/2 uses AND instead of OR when comparing filters and sorts, so same-named aggregates with different filters collide and the first value is reused. Exploitation requires the same aggregate name to reach the builder under two filter contexts, such as authorization or tenant scopes, and discloses counts, sums, or lists from excluded rows.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.1.0 <0.7.1
