CVE-2026-53426

Summary: CVE-2026-53426 affects the MDEx JSON parser. An attacker-controlled node_type in JSON fed to MDEx.parse_document/2 causes repeated String.to_atom/1 calls via Module.concat/1, creating permanent atoms and eventually exhausting the BEAM atom table. Consequence is unauthenticated denial-of-...
