CVE-2026-72923 is an uncontrolled resource consumption vulnerability in Microsoft OpenAPI.NET's YAML parsing components. It arises from nested anchors and aliases in YAML OpenAPI documents, which can cause exponential memory allocation during conversion to JSON nodes. This can lead to process termination due to out-of-memory conditions. The vulnerability affects Microsoft.OpenApi.YamlReader versions >=2.0.0-preview.11 and <2.12.0, >=3.0.0 and <3.10.0, and Microsoft.OpenApi.Readers versions <1.6.30. Patched versions are available that impose limits on node count and nesting depth to prevent unbounded expansion. The impact is limited to availability and denial of service; no code execution or data exposure is reported.
