6.9CVE-2025-3048awsaws serverless application model command line interface+1
EPSS score
0.66%
After completing a build with AWS Serverless Application Model Command Line Interface (SAM CLI) which include symlinks, the content of those symlinks are copied to the cache of the local workspace as regular files or directories. As a result, a user who does not have access to those symlinks outside of the Docker container would now have access via the local workspace. Users should upgrade to version 1.134.0 and ensure any forked or derivative code is patched to incorporate the new fixes. After upgrading, users must re-build their applications using the sam build --use-container to update the symlinks.

The AWS Cloud Development Kit (AWS CDK) is an open-source software development framework to define cloud infrastructure in code and provision it through AWS CloudFormation. Users who use IAM OIDC custom resource provider package will download CA Thumbprints as part of the custom resource workflow. However, the current `tls.connect` method will always set `rejectUnauthorized: false` which is a potential security concern. CDK should follow the best practice and set `rejectUnauthorized: true`. However, this could be a breaking change for existing CDK applications and we should fix this with a feature flag. Note that this is marked as low severity Security advisory because the issuer url is provided by CDK users who define the CDK application. If they insist on connecting to a unauthorized OIDC provider, CDK should not disallow this. Additionally, the code block is run in a Lambda environment which mitigate the MITM attack. The patch is in progress. To mitigate, upgrade to CDK v2.177.0 (Expected release date 2025-02-22). Once upgraded, users should make sure the feature flag '@aws-cdk/aws-iam:oidcRejectUnauthorizedConnections' is set to true in `cdk.context.json` or `cdk.json`. There are no known workarounds for this vulnerability.
7.9CVE-2022-31159amazonaws-sdk-java+102
EPSS score

The AWS SDK for Java enables Java developers to work with Amazon Web Services. A partial-path traversal issue exists within the `downloadDirectory` method in the AWS S3 TransferManager component of the AWS SDK for Java v1 prior to version 1.12.261. Applications using the SDK control the `destinationDirectory` argument, but S3 object keys are determined by the application that uploaded the objects. The `downloadDirectory` method allows the caller to pass a filesystem object in the object key but contained an issue in the validation logic for the key name. A knowledgeable actor could bypass the validation logic by including a UNIX double-dot in the bucket key. Under certain conditions, this could permit them to retrieve a directory from their S3 bucket that is one level up in the filesystem from their working directory. This issue’s scope is limited to directories whose name prefix matches the destinationDirectory. E.g. for destination directory`/tmp/foo`, the actor can cause a download to `/tmp/foo-bar`, but not `/tmp/bar`. If `com.amazonaws.services.s3.transfer.TransferManager::downloadDirectory` is used to download an untrusted buckets contents, the contents of that bucket can be written outside of the intended destination directory. Version 1.12.261 contains a patch for this issue. As a workaround, when calling `com.amazonaws.services.s3.transfer.TransferManager::downloadDirectory`, pass a `KeyFilter` that forbids `S3ObjectSummary` objects that `getKey` method return a string containing the substring `..` .
4.2CVE-2022-46174amazonefs-utils+10
EPSS score
0.62%
efs-utils is a set of Utilities for Amazon Elastic File System (EFS). A potential race condition issue exists within the Amazon EFS mount helper in efs-utils versions v1.34.3 and below. When using TLS to mount file systems, the mount helper allocates a local port for stunnel to receive NFS connections prior to applying the TLS tunnel. In affected versions, concurrent mount operations can allocate the same local port, leading to either failed mount operations or an inappropriate mapping from an EFS customer’s local mount points to that customer’s EFS file systems. This issue is patched in version v1.34.4. There is no recommended work around. We recommend affected users update the installed version of efs-utils to v1.34.4 or later.

EPSS score
0.69%
@awsui/components-react is the main AWS UI package which contains React components, with TypeScript definitions designed for user interface development. Multiple components in versions before 3.0.367 have been found to not properly neutralize user input and may allow for javascript injection. Users are advised to upgrade to version 3.0.367 or later. There are no known workarounds for this issue.
7.1CVE-2022-23511amazoncloudwatch_agent+2
EPSS score
0.52%
A privilege escalation issue exists within the Amazon CloudWatch Agent for Windows, software for collecting metrics and logs from Amazon EC2 instances and on-premises servers, in versions up to and including v1.247354. When users trigger a repair of the Agent, a pop-up window opens with SYSTEM permissions. Users with administrative access to affected hosts may use this to create a new command prompt as NT AUTHORITY\SYSTEM. To trigger this issue, the third party must be able to access the affected host and elevate their privileges such that they're able to trigger the agent repair process. They must also be able to install the tools required to trigger the issue. This issue does not affect the CloudWatch Agent for macOS or Linux. Agent users should upgrade to version 1.247355 of the CloudWatch Agent to address this issue. There is no recommended work around. Affected users must update the installed version of the CloudWatch Agent to address this issue.
6.4CVE-2024-45037amazonaws_cloud_development_kit+2
EPSS score
0.31%
The AWS Cloud Development Kit (CDK) is an open-source framework for defining cloud infrastructure using code. Customers use it to create their own applications which are converted to AWS CloudFormation templates during deployment to a customer’s AWS account. CDK contains pre-built components called "constructs" that are higher-level abstractions providing defaults and best practices. This approach enables developers to use familiar programming languages to define complex cloud infrastructure more efficiently than writing raw CloudFormation templates. We identified an issue in AWS Cloud Development Kit (CDK) which, under certain conditions, can result in granting authenticated Amazon Cognito users broader than intended access. Specifically, if a CDK application uses the "RestApi" construct with "CognitoUserPoolAuthorizer" as the authorizer and uses authorization scopes to limit access. This issue does not affect the availability of the specific API resources. Authenticated Cognito users may gain unintended access to protected API resources or methods, leading to potential data disclosure, and modification issues. Impacted versions: >=2.142.0;<=2.148.0. A patch is included in CDK versions >=2.148.1. Users are advised to upgrade their AWS CDK version to 2.148.1 or newer and re-deploy their application(s) to address this issue.
10CVE-2024-32888chainguardtrino+119
EPSS score
0.78%
The Amazon JDBC Driver for Redshift is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs) available in the Java Platform, Enterprise Editions. Prior to version 2.1.0.28, SQL injection is possible when using the non-default connection property `preferQueryMode=simple` in combination with application code which has a vulnerable SQL that negates a parameter value. There is no vulnerability in the driver when using the default, extended query mode. Note that `preferQueryMode` is not a supported parameter in Redshift JDBC driver, and is inherited code from Postgres JDBC driver. Users who do not override default settings to utilize this unsupported query mode are not affected. This issue is patched in driver version 2.1.0.28. As a workaround, do not use the connection property `preferQueryMode=simple`. (NOTE: Those who do not explicitly specify a query mode use the default of extended query mode and are not affected by this issue.)
7.8CVE-2024-34072awssagemaker-python-sdk+1
EPSS score
0.41%
sagemaker-python-sdk is a library for training and deploying machine learning models on Amazon SageMaker. The sagemaker.base_deserializers.NumpyDeserializer module before v2.218.0 allows potentially unsafe deserialization when untrusted data is passed as pickled object arrays. This consequently may allow an unprivileged third party to cause remote code execution, denial of service, affecting both confidentiality and integrity. Users are advised to upgrade to version 2.218.0. Users unable to upgrade should not pass pickled numpy object arrays which originated from an untrusted source, or that could have been tampered with. Only pass pickled numpy object arrays from trusted sources.

sagemaker-python-sdk is a library for training and deploying machine learning models on Amazon SageMaker. In affected versions the capture_dependencies function in `sagemaker.serve.save_retrive.version_1_0_0.save.utils` module allows for potentially unsafe Operating System (OS) Command Injection if inappropriate command is passed as the “requirements_path” parameter. This consequently may allow an unprivileged third party to cause remote code execution, denial of service, affecting both confidentiality and integrity. This issue has been addressed in version 2.214.3. Users are advised to upgrade. Users unable to upgrade should not override the “requirements_path” parameter of capture_dependencies function in `sagemaker.serve.save_retrive.version_1_0_0.save.utils`, and instead use the default value.
7.1CVE-2026-105811awsqnabot-on-aws
EPSS score

Authorization bypass through a user-controlled key in the optional Amazon Q Business Lambda hook sample ( q-business-lambda-hook https://github.com/aws-solutions-library-samples/qnabot-on-aws/blob/main/source/docs/lambda_hooks/README.md ), available with QnABot on AWS versions 7.0.0 through 7.4.5, might allow an authenticated remote user to read arbitrary Amazon S3 objects in the deploying AWS account. This sample solution provides an example Lambda hook and requires separate, manual deployment and additional setup. It is not deployed automatically with QnABot. Customers who have not deployed this optional sample hook are not affected and do not need to take action. To remediate this issue, affected customers should update the QnABot on AWS stack to version 7.4.6 or later and then redeploy the Amazon Q Business Lambda hook sample stack. Updating the QnABot on AWS stack alone does not deliver the fix.

EPSS score
0.28%
Improper control of code generation in the agent import functionality of Amazon Bedrock AgentCore Starter Toolkit before 0.3.14 might allow an authenticated same-account actor to execute arbitrary code when a user imports and runs or deploys a Bedrock Agent, via crafted configuration values incorporated into generated Python source without safe literal encoding. To remediate this issue, users should upgrade to version 0.3.14. Because this issue persists into generated source, upgrading alone is not sufficient: agents imported with an affected version must be re-imported with version 0.3.14 or later and their local and deployed output artifacts replaced.
7.3CVE-2026-16584awsaws-api-mcp-server+1
EPSS score
0.23%
Improper handling of an initialization failure in AWS API MCP Server from 0.2.13 through 1.3.46 might allow an actor to bypass the user-configured security policy and execute AWS API operations that the policy was set to deny or gate. When initialization of the security policy enforcement data fails at server startup, the policy check is skipped for the lifetime of the process. IAM permissions on the configured credentials remain in effect and are unaffected. To remediate this issue, users should upgrade to version 1.3.47.
8.3CVE-2026-16317awss2n-tls
EPSS score
0.25%
Missing validation of the outer content_type byte on TLS 1.3 encrypted records in s2n-tls allows an active man-in-the-middle to silently discard individual application data records without either endpoint detecting the modification. RFC 8446 Section 5.2 requires that the outer content_type of all encrypted TLS 1.3 records must be application_data (0x17). The s2n-tls AEAD implementation hardcodes this value in the additional authenticated data rather than using the actual wire byte, so the outer content_type is not covered by the authentication tag. This enables selective suppression of application data. In HTTP pipelining scenarios, dropping a TLS record containing an HTTP request can cause request/response desynchronization, where subsequent responses are delivered to the wrong requests. In write-heavy workloads, a dropped record containing a write request can result in undetectable data loss when the client interprets a subsequent success response as confirmation of the dropped write. All TLS 1.3 connections are affected. Both TLS clients and servers are affected. TLS 1.2 and QUIC connections are not affected. We recommend you upgrade s2n-tls to version v1.7.6
8.7CVE-2026-16756awsaws-smithy-http-server+1
EPSS score
0.75%
Missing connection and header-read timeouts and the absence of a concurrent-connection cap in the default serve() path of Amazon aws-smithy-http-server might allow remote attackers to cause a denial of service by opening many connections and sending partial requests that are never completed, exhausting server sockets and tasks. To mitigate this issue, users should upgrade to aws-smithy-http-server 0.66.5 or later.
8.4CVE-2026-16796awsbedrock-agentcore 1.18.1+1
EPSS score
0.73%
Improper neutralization of argument delimiters in the install_packages() method in AWS Bedrock AgentCore Python SDK before 1.18.1 might allow a remote authenticated user to execute arbitrary commands within the Code Interpreter sandbox via crafted package name arguments. To mitigate this issue, users should upgrade to the patched version 1.18.1.

EPSS score
0.16%
Overly permissive file permissions in AWS CLI before 1.44.78 (v1) and 2.34.29 (v2) on Unix-like systems where the umask has not been configured to restrict file permissions (the default on most systems) may allow other local users on the same host to read credentials written by certain CLI subcommands (aws codeartifact login, aws iam create-virtual-mfa-device, aws deploy register). To remediate this issue, users should upgrade to AWS CLI 1.44.78 (v1) or 2.34.29 (v2) or later.
9.8CVE-2026-13762amazoncloudfront+1
EPSS score
0.63%
Inconsistent interpretation of HTTP/2 requests in Amazon CloudFront with AWS WAF enabled might allow remote actors to bypass AWS WAF managed rule body inspection via crafted HTTP/2 requests that fragment the request body across frames so that only a partial body is inspected. This issue was remediated server-side. No customer action is required.
9.8CVE-2026-13763amazonapplication_load_balancer+1
EPSS score
0.68%
Inconsistent interpretation of HTTP/2 requests in AWS Application Load Balancer with AWS WAF enabled might allow remote actors to bypass AWS WAF managed rule body inspection via crafted HTTP/2 requests that fragment the request body across frames so that only a partial body is inspected. This issue only impacts HTTP/2 ALB target groups. To remediate this issue, customers should enable the "Inspect after sufficient data" target group configuration associated to an ALB load balancer. Refer to: ( https://docs.aws.amazon.com/elasticloadbalancing/latest/application/edit-target-group-attributes.html#waf-http2-inspection )
7.3CVE-2026-13760awsaws cdk+1
EPSS score
1.16%
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.
