CVE-2026-32875
UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Versions 5.10 through 5.11.0 are vulnerable to buffer overflow or infinite loop through large indent handling. ujson.dumps crashes the Python interpreter segmentation fault when the product of the indent...
CVE-2026-32874 UltraJSON has a Memory Leak parsing large integers allows DoS
UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Versions 5.4.0 through 5.11.0 contain an accumulating memory leak in JSON parsing large outside of the range -2^63, 2^64 - 1 integers. The leaked memory is a copy of the string form of the integer plus a...
CVE-2026-32874
UltraJSON (ujson) for Python, C-based fast JSON encoder/decoder, is affected in versions 5.4.0–5.11.0 by a memory-leak in parsing large integers that fall outside [-2^63, 2^64-1]. The leak copies the integer’s string form plus an extra NULL byte and occurs regardless of whether the integer parses...
