CVE-2026-107332 - Insecure default file permissions on cached credentials in AWS Toolkit for Visual Studio Code
Bulletin ID: 2026-129-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 10/08/2026 10:30 PM PDT Description: AWS Toolkit for Visual Studio Code is an open source extension that lets developers work with AWS services, including Amazon CodeCatalyst, from within Visual Studio Code. We identified CVE-2026-107332, an issue in the CodeCatalyst connection handler. When a user connected to a CodeCatalyst Dev Environment, the extension cached the user's CodeCatalyst bearer token to a file with world-readable permissions and did not remove the file after the session ended. A local user or process on the same machine with access to the file system was able to read this file and obtain the bearer token. Impacted versions: < 4.10.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.

CVE-2026-89090 - Denial of service in the event stream header decoder in AWS SDK for Go v2
Bulletin ID: 2026-110-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 09/11/2026 10:00 AM PDT Description: An issue exists in the the EventStream header decoder in AWS SDK for Go v2 in versions predating 2026-03-23. An actor can send a malformed EventStream response frame containing a crafted header value type byte outside the valid range, which can cause the host process to terminate. Impacted versions: < 2026-03-23 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.

CVE-2026-81838 - Zip Slip path traversal in awsdac (diagram-as-code)
Bulletin ID: 2026-090-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 08/27/2026 13:00 PM PDT Description: awsdac (diagram-as-code) is a CLI tool that generates AWS architecture diagrams from YAML definitions, enabling version-controlled, code-driven diagramming. We identified CVE-2026-81838, a Zip Slip (path traversal) issue. When awsdac extracts a zip archive referenced by a ZipFile resource in a definition file, a crafted archive can write files outside the intended cache directory, to any path writable by the user running awsdac. Depending on the file written, this can lead to arbitrary code execution. Leveraging this issue requires processing a definition file from an untrusted source. This can occur when: - awsdac is run without definition trust restrictions (versions prior to 0.22.4 had no trust distinction; version 0.22.4 and later require the −−allow−untrusted−definitions flag), or - a definition file is loaded from the local filesystem ('Type: LocalFile'), which bypasses the definition URL allowlist. CI/CD environments that process definition files from untrusted or semi-trusted sources are the primary risk scenario. awsdac is a client-side CLI tool that renders architecture diagrams locally. This issue does not affect any AWS service, AWS account, or customer data. The impact is limited to the machine on which awsdac runs. Impacted versions: awsdac: versions 0.10 through 0.23 (inclusive) Please refer to the article below for the most u
CVE-2026-85781 - Unverified access point ownership in Amazon EFS CSI Driver
Bulletin ID: 2026-099-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 09/04/2026 11:45 AM PDT Description: The Amazon EFS CSI Driver is an open-source Kubernetes Container Storage Interface (CSI) driver that lets Kubernetes workloads use Amazon EFS file systems. We identified CVE-2026-85781, an issue in the driver's volume-deletion logic. When the controller is configured with the non-default --delete-access-point-root-dir=true option, it did not verify that the EFS access point referenced by a PersistentVolume's volume handle belonged to the file system referenced by that same volume handle. An authenticated Kubernetes user with permission to create PersistentVolumes could use a crafted volume handle to cause the controller to recursively delete directories from an Amazon EFS file system that the user was not otherwise authorized to modify. This issue does not affect Amazon EFS itself; Amazon EFS access controls operated as designed. Impacted versions: <=3.4.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
