CVE-2026-81853Public exploitNetwork attack vectorHinoki check available

Sensitive-attribute disclosure via composite-key filter injection

Published Aug 31, 2026 · Updated Aug 31, 2026

Authorization bypass in Ash Framework AshAdmin 0.1.0 through 1.3.0 allows remote authenticated users to infer sensitive attribute values. AshAdmin.Helpers.decode_primary_key/2 returns a decoded composite-key map as the lookup filter without requiring its keys to match the resource's primary-key fields. Exploitation requires access to an HTTP record route, a resource with a composite primary key, and repeated guesses; successful probes disclose equality matches only.
