Kubernetes API Server - YAML Parsing DoS (Billion Laughs)

The Kubernetes API server is vulnerable to a denial of service attack via YAML/JSON parsing. An attacker can send a specially crafted YAML/JSON payload that causes exponential memory consumption Billion Laughs attack, leading to API server crash. id: CVE-2019-11253 info: name: Kubernetes API Serv...

CVE-2026-53550

js-yaml is a JavaScript YAML parser and dumper. Prior to 4.2.0, a crafted YAML document can trigger algorithmic CPU exhaustion in js-yaml merge-key processing by repeating the same alias many times in a merge sequence. This causes quadratic parse-time behavior relative to input size and can block...
