Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Polaris (polaris-core) versions before 1.4.1 insert unescaped table identifiers into Google Cloud Storage credential conditions. A caller who can request credentials for a crafted namespace or table name can get credentials that reach beyond that table, including other objects in the configured bucket. Upgrade polaris-core to 1.4.1 or later.
