SCA: security update for ujson (GHSA-c38f-wx89-p2xg)

high Tenable Cloud Security Plugin ID 441782

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Prior to
 5.12.1, when ujson.dump() writes to a file-like object and the write operation raises an exception, the
 serialized JSON string object is not decremented, leaking memory. Each failed write operation leaks the
 full size of the serialized payload. This vulnerability is fixed in 5.12.1. (CVE-2026-44660)

Solution

Update the ujson library and its related packages to version 5.12.1 or later.
