CVE-2026-82722Public exploitNetwork attack vectorHinoki check available

Node crash via client-controlled atom interning

Published Aug 31, 2026 · Updated Aug 31, 2026

Resource exhaustion in AshAdmin 0.1.0 through 1.3.0 allows remote authenticated users to crash the BEAM node via LiveView events. AshAdmin.PageLive set_actor passes client resource and domain strings to Module.concat/1, while Resource.Show calculate passes every form key to String.to_atom/1. Remote authenticated users need only reach the mounted admin LiveView; permanent atoms accumulate until the capped table forces a VM abort that interrupts every application on the node.
