    CVE-2026-67585 (GCVE-0-2026-67585)

    Vulnerability from cvelistv5 – Published: 2026-08-07 16:42 – Updated: 2026-08-07 18:12

    Title
    Atom Exhaustion via _entities Representation Keys in DivvyPayHQ absinthe_federation
    Summary
    Allocation of Resources Without Limits or Throttling vulnerability in DivvyPayHQ absinthe_federation allows an unauthenticated remote attacker to abort the Erlang VM via crafted _entities representation keys. Every key of every object in the representations argument of the federation-mandated _entities field is converted with String.to_atom/1 by convert_key/2 in lib/absinthe/federation/schema/entities_field.ex. representations is typed as the open-ended _Any scalar, so its keys bypass schema coercion and the attacker names them freely. Atoms are never garbage collected and the BEAM atom table is hard-capped (about 1,048,576 entries by default), so one request carrying tens of thousands of unique keys creates that many permanent atoms and a handful of such requests exhausts the table and aborts the node. The impact is confined to availability: no data is read or altered, and recovery requires restarting the application. This issue affects absinthe_federation: from 0.1.0 before 0.9.3.
