CVE-2026-6912 is a high-severity vulnerability in AWS Ops Wheel affecting the Cognito User Pool configuration. It allows remote authenticated users to escalate privileges to deployment admin by exploiting improper control over dynamically-determined object attributes via a crafted UpdateUserAttributes API call. This enables attackers to set the custom:deployment_admin attribute and manage Cognito user accounts. The vulnerability is present before pull request #165 and affects version 0 of AWS Ops Wheel. AWS manages remediation for this cloud service and has released a fix. Users should redeploy from the updated repository and patch any forked or derivative code accordingly.
Missing JWT signature verification in AWS Ops Wheel allows unauthenticated attackers to forge JWT tokens and gain unintended administrative access to the application, including the ability to read, modify, and delete all application data across tenants and manage Cognito user accounts within the deployment's User Pool, via a crafted JWT sent to the API Gateway endpoint.
To remediate this issue, users should redeploy from the updated repository and ensure any forked or derivative code is patched to incorporate the new fixes.
Cryptographic algorithm downgrade in the caching layer of Amazon AWS Encryption SDK for Python before version 3.3.1 and before version 4.0.5 might allow an authenticated local threat actor to bypass key commitment policy enforcement via a shared key cache, resulting in ciphertext that can be decrypted to multiple different plaintexts.
To remediate this issue, users should upgrade to version 3.3.1, 4.0.5 or above.
An out-of-bounds write issue in the virtio PCI transport in Firecracker 1.13.0 through 1.14.3 and 1.15.0 on x86_64 and aarch64 might allow a local guest user with root privileges to crash the Firecracker VMM process or potentially execute arbitrary code on the host via modification of virtio queue configuration registers after device activation. Achieving code execution on the host requires additional preconditions, such as the use of a custom guest kernel or specific snapshot configurations.
To remediate this, users should upgrade to Firecracker 1.14.4 or 1.15.1 and later.
CVE-2026-5709 is a high-severity OS command injection vulnerability in AWS Research and Engineering Studio (RES) versions 2024.10 through 2025.12.01. It arises from unsanitized input in the FileBrowser API, allowing a remote authenticated user to execute arbitrary commands on the cluster-manager EC2 instance. AWS has released a fix in RES version 2026.03 and provides a mitigation patch for existing environments. This vulnerability requires authenticated access and does not have known exploits in the wild at this time.
CVE-2026-5708 is a high-severity vulnerability in AWS Research and Engineering Studio (RES) prior to version 2026.03. It involves improper control of user-modifiable attributes during session creation, allowing an authenticated remote user to escalate privileges and assume the virtual desktop host instance profile permissions. This could enable interaction with AWS resources and services beyond intended access. AWS manages the remediation for this cloud service and advises upgrading to version 2026.03 or applying the corresponding mitigation patch. No known exploits in the wild have been reported.
Unsanitized input in an OS command in the virtual desktop session name handling in AWS Research and Engineering Studio (RES) version 2025.03 through 2025.12.01 might allow a remote authenticated actor to execute arbitrary commands as root on the virtual desktop host via a crafted session name.
To remediate this issue, users are advised to upgrade to RES version 2026.03 or apply the corresponding mitigation patch to their existing environment.
Unsanitized input during web page generation in the Kiro Agent webview in Kiro IDE before version 0.8.140 allows a remote unauthenticated threat actor to execute arbitrary code via a potentially damaging crafted color theme name when a local user opens the workspace. This issue requires the user to trust the workspace when prompted.
To remediate this issue, users should upgrade to version 0.8.140.
Out-of-bounds write in the streaming decoder component in aws-c-event-stream before 0.6.0 might allow a third party operating a server to cause memory corruption leading to arbitrary code execution on a client application that processes crafted event-stream messages.
To remediate this issue, users should upgrade to version 0.6.0 or later.
A logic error in CRL distribution point validation in AWS-LC before 1.71.0 causes partitioned CRLs to be incorrectly rejected as out of scope, which allows a revoked certificate to bypass certificate revocation checks.
To remediate this issue, users should upgrade to AWS-LC 1.71.0 or AWS-LC-FIPS-3.3.0.
CVE-2026-4295 is a high-severity vulnerability in AWS Kiro IDE versions before 0.8.0 that allows remote unauthenticated attackers to execute arbitrary code. The issue arises from improper trust boundary enforcement, specifically CWE-829, where maliciously crafted project directory files can bypass workspace trust protections when a local user opens the directory. Exploitation requires the attacker to place malicious files in a project directory that a user subsequently opens in the IDE, triggering code execution. Although no known exploits are currently in the wild, the vulnerability impacts confidentiality, integrity, and availability with a CVSS score of 7.8. Users should upgrade to version 0.8.0 or later to remediate the issue.
A missing S3 ownership verification in the Bedrock AgentCore Starter Toolkit before version v0.1.13 may allow a remote actor to inject code during the build process, leading to code execution in the AgentCore Runtime. This issue only affects users of the Bedrock AgentCore Starter Toolkit before version v0.1.13 who build or have built the Toolkit after September 24, 2025. Any users on a version >=v0.1.13, and any users on previous versions who built the toolkit before September 24, 2025 are not affected.
To remediate this issue, customers should upgrade to version v0.1.13.
Improper Protection of Alternate Path exists in the no-access and workdir feature of the AWS API MCP Server versions >= 0.2.14 and < 1.3.9 on all platforms may allow the bypass of intended file access restriction and expose arbitrary local file contents in the MCP client application context.
To remediate this issue, users should upgrade to version 1.3.9.
Improper signature validation in PKCS7_verify() in AWS-LC allows an unauthenticated user to bypass signature verification when processing PKCS7 objects with Authenticated Attributes.
Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
Observable timing discrepancy in AES-CCM decryption in AWS-LC allows an unauthenticated user to potentially determine authentication tag validity via timing analysis.
The impacted implementations are through the EVP CIPHER API: EVP_aes_128_ccm, EVP_aes_192_ccm, and EVP_aes_256_ccm.
Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
Improper certificate validation in PKCS7_verify() in AWS-LC allows an unauthenticated user to bypass certificate chain verification when processing PKCS7 objects with multiple signers, except the final signer.
Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
Omega-PSIR is vulnerable to Reflected XSS via the lang parameter. An attacker can craft a malicious URL that, when opened, causes arbitrary JavaScript to execute in the victim’s browser.
This issue was fixed in 4.6.7.
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Spencer Haws Link Whisper Free link-whisper allows Reflected XSS.This issue affects Link Whisper Free: from n/a through <= 0.9.2.
The Easy Author Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'author_profile_picture_url' parameter in all versions up to, and including, 1.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
