Summary
cjson vulnerabilities
Details
It was discovered that cJSON incorrectly handled parsing large numbers. An attacker could possibly use this issue to cause a denial of service. (CVE-2023-26819)
It was discovered that cJSON may perform out-of-bounds read when processing specially crafted JSON files using parse_object. An attacker could possibly use this issue to expose sensitive information or crash the program. (CVE-2023-53154)
It was discovered that cJSON incorrectly validated array indices in JSON pointers, which could result in an out-of-bounds memory access. An attacker could possibly use this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-57052)
