CVE-2026-94201
Description
A flaw was found in ash. When filtering data using atom-typed attributes configured to permit string conversion, input values are converted into permanent internal symbols (atoms) that cannot be garbage-collected. A remote attacker can exploit this vulnerability by submitting queries with numerous distinct filter values to exhaust the runtime environment's symbol table. This can cause the application node to crash, resulting in a Denial of Service (DoS).
