CVE-2026-42793Public exploitNetwork attack vector

Node crash via unbounded GraphQL SDL atoms

Published May 8, 2026 · Updated May 8, 2026

Resource exhaustion in Absinthe 1.5.0 through 1.10.1 allows remote attackers to crash the Erlang node via crafted GraphQL SDL. Blueprint.Draft.convert/2 calls String.to_atom/1 on untrusted directive, field, type, and argument names, permanently filling the fixed BEAM atom table. Exploitation requires an application to parse attacker-controlled SDL; exhaustion aborts the VM with system_limit and interrupts the entire node.
