In addition, deploying a poisoned model in Vertex AI led to the exfiltration of all other fine-tuned models, posi…
A vulnerability in Amazon DataZone allowed potential attackers to assume roles in AWS accounts by exploiting a confused deputy problem. This could have granted unauthorized access to sensitive data managed by DataZone or other AWS services accessible by the IAM role trusting DataZone. The issue has been resolved, with no customers reportedly impacted.
A technique called "repo swatting" allows attackers to delete GitHub and block GitLab accounts by exploiting file upload features and abuse reporting mechanisms. Attackers upload malicious files to a target's repository, then report the account for hosting malicious content, potentially resulting in account deletion. The vulnerability was partially mitigated by October 2024 via changes in upload URL paths and requirement for each uploader to be authenticated (in GitHub).
The AWS Cloud Development Kit (CDK) is a way of deploying infrastructure-as-code. The vulnerability involves AWS CDK’s use of a predictable S3 bucket name format (cdk-{Qualifier}-assets-{Account-ID}-{Region}), where the default “random” qualifier (hnb659fds) is common and easily guessed. If an AWS customer deletes this bucket and reuses CDK, an attacker who claims the bucket can inject malicious CloudFormation templates, potentially gaining admin access. Attackers supposedly only need the AWS a…

This issue potentially bypassed existing controls aimed at preventing lateral movement and access to higher-privileged management roles.
A vulnerability in GitLab Pages allowed attackers to take over dangling custom domains pointing to 'instanceX.gitlab.io'. The issue occured when adding an unverified custom domain to GitLab Pages, which serves content for 7 days before disabling. This could lead to cookie stealing, phishing campaigns, and bypassing of Content-Security Policies and CORS.
Multiple "pwn request" vulnerabilities were discovered in Google Cloud Data Fusion, which is based on open-source CDAP code. These vulnerabilities affect GitHub Actions and allow for remote code execution (RCE) and compromise of build artifacts. The issues potentially impact both the Google Cloud platform and GitHub's CI/CD infrastructure.
Google Cloud Composer is a managed service for Apache Airflow. Tenable discovered that the Cloud Composer package was vulnerable to dependency confusion, which could have allowed attackers to inject malicious code when the package was compiled from source. This could have led to remote code execution on machines running Cloud Composer, which include various other GCP services as well as internal servers at Google. The dependency confusion stemmed from Google's risky recommendation in their docu…
The Document AI service unintentionally allows users to read any Cloud Storage object in the same project, in a way that isn't properly documented. The Document AI service agent is auto-assigned with excessive permissions, allowing it to access all objects from Cloud Storage buckets in the same project. Malicious actors can exploit this to exfiltrate data from Cloud Storage by indirectly leveraging the service agent's permissions. This vulnerability is an instance of transitive access abuse, a …
