Summary
ujson vulnerabilities
Details

It was discovered that UltraJSON incorrectly handled certain input with a large amount of indentation. An attacker could possibly use this issue to crash the program, resulting in a denial of service. (CVE-2021-45958)

Jake Miller discovered that UltraJSON incorrectly decoded certain characters. An attacker could possibly use this issue to cause key confusion and overwrite values in dictionaries. (CVE-2022-31116)

It was discovered that UltraJSON incorrectly handled an error when reallocating a buffer for string decoding. An attacker could possibly use this issue to corrupt memory. (CVE-2022-31117)
