Please do not open a public issue for a security problem. Use the private vulnerability reporting form of this repository, and include the input that triggers the problem and the compiler you used.

• The parser returns a tree or throws json::parser_error. Catch it.
• Nesting is limited by json::config::max_depth (default 256). Lower it if you do not need deep documents.
• The parser keeps the whole document in memory, in addition to the tree built from it. Limit the size of the input you accept.
• json::config holds global variables. Set them once at startup.
