Apache Polaris has an Improper Input Validation issue

In Apache Iceberg, the table's metadata files are control files: they tell readers which data files belong to the table and which table version to read. write.metadata.path is an optional table property that tells Polaris where to write those metadata files. For a table already registered in a...

Apache Polaris has an Improper Input Validation issue

In plain terms, Apache Polaris is supposed to issue short-lived GCS credentials that only work for one table's files, but a crafted namespace or table name can cause those credentials to work across the configured bucket instead. Apache Polaris builds Google Cloud Storage downscoped credentials b...

Apache OpenNLP ExtensionLoader Vulnerable to Arbitrary Class Instantiation via Model Manifest

Arbitrary Class Instantiation via Model Manifest in Apache OpenNLP ExtensionLoader Versions Affected: before 2.5.9, before 3.0.0-M3 Description: The ExtensionLoader.instantiateExtensionClass, String method loads a class by its fully-qualified name via Class.forName and invokes its no-arg...
