MGASA-2026-0073 Updated python-ujson packages fix security vulnerabilities

CVE-2026-32874 ujson 5.4.0 to 5.11.0 inclusive contains an accumulating memory leak in JSON parsing large outside of the range -2^63, 2^64 - 1 integers. ujson 5.4.0 to 5.11.0 has an integer overflow while handling a large indent which leads to a buffer overflow or infinite loop...

CVE-2026-32874

A flaw was found in UltraJSON, a fast JSON encoder and decoder. A remote attacker can exploit this vulnerability by providing specially crafted JSON input that contains extremely large integers. When UltraJSON attempts to parse these inputs, it leads to an accumulating memory leak. This excessive...
