CVE-2026-82748Public exploitHinoki check available

Restricted aggregate disclosure via mismatched read actions

Published Sep 1, 2026 · Updated Sep 1, 2026

Incorrect authorization in Ash 3.5.13 through 3.32.1 allows attackers to disclose restricted aggregate counts. Ash.Actions.Aggregate authorizes each group against its read_action but builds the data query with a caller-supplied action, applying different policies. Exposure requires an application to supply both actions and expose the aggregate; the result reveals counts or sums over records that the authorized action excludes.
