CVE-2026-42810 [CRITICAL] CWE-20 CVE-2026-42810: Apache Polaris accepts literal `*` characters in namespace and table names. When it later builds tem Apache Polaris accepts literal `*` characters in namespace and table names. When it later builds temporary S3 access policies for delegated table access, those same characters appear to be reused unescaped in S3 IAM resource patterns and `s3:prefix` conditions. In S3 IAM policy matching, `*` is treated as a wildcard rather than as ordinary text.

CVE-2026-42811 [CRITICAL] CWE-20 CVE-2026-42811: In plain terms, Apache Polaris is supposed to issue short-lived GCS credentials that only work for o 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 by creating a Credential Access Boundary (CAB) with

CVE-2026-42812 [CRITICAL] CWE-20 CVE-2026-42812: In Apache Iceberg, the table's metadata files are control files: they tell readers which data files 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 Polaris-managed catalog, changing only that property

CVE-2026-42809 [CRITICAL] CWE-20 CVE-2026-42809: Apache Polaris can issue broad temporary ("vended") storage credentials during staged table creation Apache Polaris can issue broad temporary ("vended") storage credentials during staged table creation before the effective table location has been validated or durably reserved. Those temporary credentials are meant to limit the scope of accessible table data and metadata, but this scope limitation becomes attacker- directed because the attacker can
