CVE-2026-45304
CVE-2026-45304 affects Symfony’s YAML Parser (Symfony\Component\Yaml\Parser). Before versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12, the parser resolved YAML collection aliases recursively, enabling a small untrusted YAML input to expand into a multi-gigabyte structure and exhaust memory. Impact is ...

CVE-2026-59869
A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker could exploit this vulnerability by providing a specially crafted YAML document containing a chain of mappings with merge keys. This could cause the parser to consume excessive CPU resources, leading to a Denial o...
