Details
It was discovered that SnakeYAML did not limit the maximal nested depth
for collections when parsing YAML data. If a user or automated system were
tricked into opening a specially crafted YAML file, an attacker could
possibly use this issue to cause applications using SnakeYAML to crash,
resulting in a denial of service. (CVE-2022-25857, CVE-2022-38749,
CVE-2022-38750)
It was discovered that SnakeYAML did not limit the maximal data matched
