CVE-2026-126793

Privilege escalation in Aurora PostgreSQL dialect detection in AWS Advanced Go Wrapper

An untrusted search path issue in Aurora PostgreSQL dialect detection in the AWS Advanced Go Wrapper from release 2026-04-06 (awssql/v2.0.0) and before release 2026-07-29 (awssql/v2.0.3) could allow a remote authenticated user to escalate privileges to those of another database user, including a member of the rds_superuser role, via a crafted function that runs when that user connects to an Aurora PostgreSQL cluster through an affected version of the wrapper. To remediate this issue, users should upgrade to the AWS Advanced Go Wrapper release 2026-07-29 (awssql/v2.0.3) or later.

CVE-2026-127119

Unverified ownership of the default EMR cluster log location in AWS SDK for pandas

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.

Untrusted search path in the cross-user process launcher in OpenJD Sessions for Python, as used in the AWS Deadline Cloud worker agent

Untrusted search path in the cross-user process launcher in Open Job Description (OpenJD) Sessions for Python before 0.11.0, as used in the AWS Deadline Cloud worker agent before 0.33.0, on Linux might allow an authenticated remote user with permission to submit jobs to a queue to execute arbitrary code as the worker agent OS user and obtain the AWS credentials held by the worker agent via a crafted job that modifies the PATH environment variable. To remediate this issue, users of customer-managed fleets should upgrade the Deadline Cloud worker agent to version 0.33.0 or later, which includes OpenJD Sessions 0.11.0. Service-managed fleets were remediated service-side.

Relative path traversal in the log export commands in AWS ParallelCluster CLI

The export-cluster-logs and export-image-logs commands in the AWS ParallelCluster CLI before version 3.16.0 contain a relative path traversal issue. An authenticated remote user with write access to the log export Amazon S3 bucket could use a crafted S3 object key to write files outside the intended export directory on the machine running the command. The written files would have names and content controlled by a third party, and would be created with the privileges of the user running the command. To remediate this issue, users should upgrade to version 3.16.0 or later.

CVE-2026-119924

Out-of-Bounds Read in Babelfish for PostgreSQL TDS RPC Procedure-Name Parser

An out-of-bounds read in the TDS RPC procedure-name parser in the Babelfish for PostgreSQL extension versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish might allow remote authenticated users to read adjacent process memory or cause a denial of service via a malformed TDS RPC request to the TDS port (default 1433). To remediate this issue, we recommend users upgrade to Babelfish for PostgreSQL extension versions 4.10, 5.6, 6.1 or later. As a workaround, restrict network access to the TDS port (default 1433). Customers using Amazon Aurora PostgreSQL with Babelfish should upgrade their cluster to Aurora PostgreSQL 13.9.16 (1.5.5), 13.23.3 (1.17.2), 14.6.16 (2.3.5), 14.17.8 (2.12.4), 14.18.6 (2.13.3), 14.19.5 (2.14.2), 14.20.5 (2.15.2), 14.22.3 (2.16.1), 14.23.1 (2.17.0), 15.10.8 (3.8.4), 15.12.8 (3.9.4), 15.13.6 (3.10.3), 15.14.5 (3.11.2), 15.15.5 (3.12.2), 15.17.3 (3.13.1), 15.18.1 (3.14.0), 16.8.8 (4.5.5), 16.9.6 (4.6.3), 16.10.5 (4.7.2), 16.11.5 (4.8.2), 16.13.3 (4.9.1), 16.14.1 (4.10.0), 17.4.8 (5.1.4), 17.5.6 (5.2.3), 17.6.5 (5.3.2), 17.7.5 (5.4.2), 17.9.3 (5.5.1), 17.10.1 (5.6.0), 18.3.4 (6.0.2), 18.4.1 (6.1.0) or later, and apply any pending maintenance to ensure they are on the latest patch.

CVE-2026-119923

Heap-based Buffer Overflow in Babelfish for PostgreSQL TDS Prelogin Parser

A heap-based buffer overflow in the TDS prelogin parser in the Babelfish for PostgreSQL extension versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish might allow remote attackers to execute arbitrary OS commands as the database process user via a specially crafted malformed TDS prelogin packet to the TDS port. This record consolidates a related NULL-pointer-dereference finding in the same prelogin parser. To remediate this issue, we recommend users upgrade to Babelfish for PostgreSQL extension versions 4.10, 5.6, 6.1 or later. As a workaround, restrict network access to the TDS port (default 1433). Customers using Amazon Aurora PostgreSQL with Babelfish should upgrade their cluster to Aurora PostgreSQL 13.9.16 (1.5.5), 13.23.3 (1.17.2), 14.6.16 (2.3.5), 14.17.8 (2.12.4), 14.18.6 (2.13.3), 14.19.5 (2.14.2), 14.20.5 (2.15.2), 14.22.3 (2.16.1), 14.23.1 (2.17.0), 15.10.8 (3.8.4), 15.12.8 (3.9.4), 15.13.6 (3.10.3), 15.14.5 (3.11.2), 15.15.5 (3.12.2), 15.17.3 (3.13.1), 15.18.1 (3.14.0), 16.8.8 (4.5.5), 16.9.6 (4.6.3), 16.10.5 (4.7.2), 16.11.5 (4.8.2), 16.13.3 (4.9.1), 16.14.1 (4.10.0), 17.4.8 (5.1.4), 17.5.6 (5.2.3), 17.6.5 (5.3.2), 17.7.5 (5.4.2), 17.9.3 (5.5.1), 17.10.1 (5.6.0), 18.3.4 (6.0.2), 18.4.1 (6.1.0) or later, and apply any pending maintenance to ensure they are on the latest patch.
