Summary

Details

Mojo::JSON versions before 9.47 for Perl allow memory exhaustion via unbounded recursion in the pure-Perl decoder. The pure-Perl decode path (_decode_value dispatching to _decode_array and _decode_object) 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 MOJO_NO_JSON_XS=1 is set; the Cpanel::JSON::XS fast path is not affected. Any caller that decodes an untrusted JSON body, for example Mojo::Message::json reached through $c->req->json, can exhaust process memory and cause denial of service.
