CVE-2026-127119 Unverified ownership of the default EMR cluster log location in AWS SDK for pandas

5.9 mediumEPSS 0.2%

Medium (5.9) in aws aws-sdk-pandas. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.

On this page
Unverified ownership of the default cluster log location in the EMR module in AWS SDK for pandas (awswrangler) from 1.1.0 before 3.18.0 might allow remote actors to read Amazon EMR cluster logs, including job step output, via a pre-created S3 bucket. To remediate this issue, users should upgrade to version 3.18.0 or later. Users who can't upgrade immediately should pass an explicit log location, or create the default EMR log bucket in their own account in each region they use.
