CVE-2026-55563— Feast: `pull_request_target` integration tests run untrusted fork code with production cloud secrets; the `ok-to-test` label guard is bypassable via label persistence on `synchronize`

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Feast 是一个面向人工智能和机器学习的开源特征存储平台。在 0.65.0 版本之前， 工作流使用了 触发器，并配合 事件，在每次新推送的提交中保留了 、 或 等标签。这使得 fork 的开发者能够先获得对某个看似无害的修订版本的批准，随后通过 引用执行已修改的代码，并利用受保护的 目标执行特权操作。 该工作流会将 GCP、AWS 和 Snowflake 的凭据暴露给这段代码，从而导致运行器（runner）代码执行、凭据泄露，并可能进一步访问下游云资源。虽然引入外部的标签移除集成机制可以缓解此问题，但该仓库的工作

Vulnerability Title
Feast: `pull_request_target` integration tests run untrusted fork code with production cloud secrets; the `ok-to-test` label guard is bypassable via label persistence on `synchronize`
Source: CVE Program / CVE List V5
Vulnerability 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.
