3.17.5 - 2026-07-31

Most of this release comes out of a security review of the C extension. There are no API changes.

Memory safety

• Fixed hash flooding by seeding the key hash per process. The hash was decided entirely at compile time, so a document of colliding keys turned key interning into O(n^2) and left the process slow for every later parse. (#1053)
• Fixed a one byte buffer over-read on a document that ends with a backslash inside an unterminated string. (#1054)
• Fixed two length underflows that made an empty ^m value and a key of exactly 65,536 bytes read forward until they left mapped memory. (#1055)
• Fixed a SEGV from type confusion in class path resolution. A name segment that resolved to something other than a class or module was dereferenced as one. (#1056)
• Fixed uninitialized stack memory being read into the message of an unresolved class name error. (#1057)
• Fixed output buffer overflows when writing indentation, where several callers of fill_indent() had not assured the buffer first. (#1058)
• Fixed the Oj::Doc path depth limit being checked one level too late. (#1061)
• Fixed the use-after-free of a key when the value stack grows. (#1062)
• Fixed the buffer over-read when a document ends where a key belongs. (#1063)
• Fixed the id from a circular reference being used unchecked. (#1064)
• Fixed the SEGV dumping an exception that was never raised, where the missing backtrace was read as an Array. (#1068)
• Fixed the stack buffer overflow writing the error location. (#1071)
• Fixed a read error in Oj::Parser#file being taken as a read of SIZE_MAX bytes, which wrote in front of the buffer and then reparsed it forever without checking for interrupts. (#1072)
• Fixed a :float_format too long for the 64 byte buffer copying stack bytes past the end of it into the output. (#1073)
• Fixed the double free of the default create_id when a call passes :create_id => nil. (#1074)
• Fixed the buffer over-read of an odd attribute name and the leak of its arguments. (#1075)
• Fixed the SEGV reading a truncated document with Oj::Parser#file and the descriptor it leaked. (#1076)
• Fixed the SEGV from a malformed number in Oj::Doc. (#1077)
• Fixed the stack exhaustion from a long key with :only or :except. (#1078)
• Fixed the odd module match being decided by uninitialized memory. (#1079)
• Fixed :float_format accepting directives it has no argument for. (#1083)

Memory leaks

• Fixed the leak of an escaped hash key in the streaming parser. (#1067)
• Fixed the leak of the parser create_id when it is set a second time. (#1085)
• Fixed the leak of the parser when Oj::Parser.new or Oj::Parser.safe raises on an argument it does not take. (#1086)

Parsing and dumping

• Fixed a safe parser limit of 4 being ignored. (#1065)
• Fixed the exponent bound being checked after it is narrowed. (#1066)
• Fixed a document being rejected when it opens with a number of 4093 digits or more read through a file descriptor or an IO, and the reader buffer that leaked when it grew. (#1069)
• Fixed the safe parser limits being dropped when an option is set after the parser is built. (#1070)
• Fixed the :custom mode dump of an exception that was never raised opening with {,. (#1082)
• Fixed the :wab mode time load being an offset out on Windows, where mktime() stood in for timegm() and returned -1 for any time before the epoch. (#1088)
• Fixed Oj::Doc dropping the exponent of a number written without a decimal point, so 1e3 loaded as 1. (#1089)

Rails

• Fixed a to_json(only:) or to_json(except:) dropping the include_root_in_json wrapper key and the keys added by :methods. (#1039)
• Fixed the as_json options reaching only the first element of a container, so to_json(only:), to_json(methods:) and any custom as_json(opts) took effect on one row and nowhere else. (#1040)
• An encoder now reads the global optimized class table and options instead of copying them, saving about 6.7KB of malloc per ActiveSupport::JSON.encode, and picks up later Oj.default_options and ActiveSupport::JSON::Encoding changes. (#1049)
• Fixed as_json being handed the encoder's own options hash. ActiveSupport allows as_json to write into it, and ActiveSupport 8.1 caches one encoder per process, so a single such as_json could leave :only set for every later to_json. (#1050)
