CVE-2026-55563
Feast is the open source feature store for AI and machine learning.
Overview
CVE-2026-55563 is a known-severity vulnerability. It was published on September 21, 2026.
Technical 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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-55563?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-55563 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
