NVD Description

Note: Versions mentioned in the description apply only to the upstream label-studio package and not the label-studio package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
