  "title": "Unvalidated KMS URL forwarding in Apache Parquet and PyArrow",
  "summary": "Apache C++ Parquet and PyArrow versions 4.0.0 through 25.0.1 can forward a KMS URL from a Parquet file to a configured KMS client without validating its host. An attacker may cause a KMS token to be sent to an attacker-controlled host when a target reads a file using decryption settings that allow the file to control the KMS URL.",
  "mitigation": "Upgrade to version 26.0.0, where file-controlled KMS URLs are disabled by default. Otherwise, configure the KMS URL in KmsConnectionConfig and ensure KmsClient implementations validate KMS URL hosts.",
