CVE-2026-72923
Microsoft.OpenApi.YamlReader (versions 2.0.0-preview.11 through 2.12.0 and 3.0.0 through 3.10.0) and Microsoft.OpenApi.Readers (prior to 1.6.30) are vulnerable to a denial of service via YAML alias expansion. The root cause lies in how SharpYaml represents aliases as shared nodes in a directed ac...
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 ...
Symfony's YAML Parser Vulnerable to Exponential Memory Allocation via Recursive Collection-Alias Expansion ("Billion Laughs")
Description Symfony\Component\Yaml\Parser resolves YAML aliases anchor during parsing. Aliases that reference collections arrays, stdClass, TaggedValue-wrapped collections can themselves point to other collections containing aliases, creating exponential expansion at resolution time. A small inpu...
