The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow.

Exploit prediction (EPSS)

6.96% probability of exploitation in the next 30 days, higher than 94% of all scored CVEs.
