  "title": "libmojolicious-perl: Mojo::JSON versions before 9.47 for Perl allow memory exhaustion via unbounded recursion in the pure-Perl decoder",
  "description": "Mojo::JSON versions before 9.47 for Perl allow memory exhaustion via unbounded recursion in the pure-Perl decoder.  The pure-Perl decode path (\u0060_decode_value\u0060 dispatching to \u0060_decode_array\u0060 and \u0060_decode_object\u0060) recurses with no depth limit, so a small deeply nested JSON document can consume excessive memory.  This path is the default when Cpanel::JSON::XS is not installed or \u0060MOJO_NO_JSON_XS=1\u0060 is set; the Cpanel::JSON::XS fast path is not affected.  Any caller that decodes an untrusted JSON body, for example \u0060Mojo::Message::json\u0060 reached through \u0060$c-\u003Ereq-\u003Ejson\u0060, can exhaust process memory and cause denial of service.",
