CVE-2022-31117 is a double-free vulnerability in UltraJSON versions prior to 5.4.0, a fast JSON encoder/decoder for Python. This flaw, specifically CWE-415, occurs during buffer reallocation for string decoding. Rated Medium (CVSS 5.9), it has a high attack complexity and could lead to a denial of service, though it is not triggerable from Python due to UltraJSON's internal decoder usage. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
