Heap-based buffer overflow in the parse_string function in libs/esl/src/esl_json.c in FreeSWITCH before 1.4.23 and 1.6.x before 1.6.2 allows remote attackers to execute arbitrary code via a trailing \u in a json string to cJSON_Parse.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.67%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
