CVE-2026-14904

RES Auth.GetUserPrivateKey Arbitrary File Read

AWS Research and Engineering Studio (RES) is an open-source solution that enables researchers and engineers to create and manage secure virtual desktops and computing resources on AWS. Improper link resolution before file access issue (CWE-59) in the Auth.GetUserPrivateKey API. An authenticated remote user could read arbitrary files on the cluster-manager EC2 instance by replacing their SSH private key file (~/.ssh/id_rsa) with a symbolic link targeting any file on the host. Because the cluster-manager process runs as root, any file readable by root is exposed, including other users' SSH private keys and application configuration secrets. It's recommended to upgrade to RES version 2026.06.

RCE via Deserialization in AWS Advanced JDBC Wrapper

Deserialization of untrusted data in the RemoteQueryCachePlugin in Amazon Web Services AWS Advanced JDBC Wrapper 3.3.0 through 4.0.0 might allow an actor with write access to the shared cache infrastructure to execute arbitrary code on application servers that read cached query results via a crafted serialized Java object. The RemoteQueryCachePlugin uses ObjectInputStream without class filtering when deserializing cached query results from Redis or Valkey, enabling gadget chain execution when cache entries are poisoned. We recommend upgrading to AWS Advanced JDBC Wrapper version 4.0.1 or later.

OS Command Injection in aws-cdk-lib Docker Bundling

OS command injection in the NodejsFunction Docker bundling pipeline (OsCommand helper) in AWS aws-cdk-lib on all platforms might allow a actor who controls dependency version strings in a project's package.json file to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters in the OsCommand helper. This issue requires the actor to control the content of a package.json dependency version string that is processed during Docker-based bundling with nodeModules specified. To remediate this issue, users should upgrade to v2.260.0.

Insecure Permissions on Authentication Token Cache File in Kiro IDE

Incorrect default permissions in Kiro IDE on macOS and Linux before version 0.11.133 could expose the authentication token cache file to other local users or processes via world-readable permissions (0644) instead of owner-restricted permissions (0600). To remediate this issue, users should upgrade to Kiro IDE version 0.11.133 or later. After upgrading and restarting the application, the cache file permissions are automatically updated on the next token refresh. Users operating in a multi-user environment can invalidate existing tokens by reauthenticating.

OS Command Injection in NodejsFunction Bundling in aws-cdk-lib

OS command injection in the NodejsFunction local bundling pipeline in aws-cdk-lib before 2.245.0 (2.246.0 on Windows) might allow an actor who controls the value of one or more bundling properties (externalModules, define, loader, inject, or esbuildArgs) to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters. This issue requires the threat actor to control the value of one or more of the affected bundling properties in the CDK application. To remediate this issue, users should upgrade to aws-cdk-lib 2.245.0 (2.246.0 on Windows) or later.
