CVE-2026-127119 - Unverified ownership of the default EMR cluster log location in AWS SDK for pandas
Bulletin ID: 2026-181-AWS Publication Date: 11/12/2026 13:00 PM PST Description: We identified CVE-2026-127119, an issue in the EMR module of AWS SDK for pandas (awswrangler) from version 1.1.0 before 3.18.0. When a cluster is created without an explicit log location, the library uses a predictable default S3 bucket name for the cluster logs without verifying that the caller's account owns that bucket. A remote actor who creates that bucket first could read the cluster's logs, including job step output. Impacted versions: >= 1.1.0 AND Refer to the article for the most up-to-date and complete information.
