CyberRota Analysis

AI-Generated

The vulnerability in Feast prior to version 0.65.0 allows fork contributors to exploit the pull_request_target event in GitHub workflows, potentially executing malicious code with elevated privileges and exposing sensitive credentials for GCP, AWS, and Snowflake. This could lead to unauthorized access to cloud resources and significant data breaches. Organizations using Feast for AI and machine learning should prioritize upgrading to version 0.65.0 to mitigate these risks.

Original NVD Description

Feast is the open source feature store for AI and machine learning. Prior to 0.65.0, .github/workflows/pr_integration_tests.yml uses pull_request_target with the synchronize event and preserves ok-to-test, approved, or lgtm labels across newly pushed commits, allowing a fork contributor to obtain approval for a benign revision and then run changed code from refs/pull/${{ github.event.pull_request.number }}/merge through privileged make targets. The job exposes GCP, AWS, and Snowflake credentials to that code, enabling runner code execution, credential disclosure, and possible access to downstream cloud resources. An external label-removal integration could mitigate the condition, but no repository workflow provided that protection. This issue is fixed in version 0.65.0.
