CVE-2026-81633Public exploitNetwork attack vectorHinoki check available

Stack-trace disclosure via unvalidated relay type

Published Aug 30, 2026 · Updated Aug 30, 2026

Improper input validation in Ash Framework AshGraphql 0.27.0 through 1.10.1 allows remote attackers to crash relay node queries. resolve_node/2 base64-decodes and splits the supplied global ID without validating its type segment, then passes that segment to Map.fetch!, which raises on an unmapped atom. An application must expose the AshGraphql relay node field over HTTP; exploitation requires no authentication and interrupts only the request while disclosing error details.
