CVE-2026-46618— Fission 操作系统命令注入漏洞

Fission builder accepts arbitrary buildcmd strings from Environment.spec.builder.command, allowing the builder pod to invoke arbitrary executables

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, before the round-1 security sweep, pkg/builder/builder.go passed Environment.spec.builder.command directly into exec.Command(...) after a strings.Fields split, with no validation of the executable path or its arguments. A user who could create or update Environment CRDs in a namespace observed by the buildermgr could thereby point the builder pod at any executable inside the builder image (e.g. /bin/sh -c '...') and execute arbitrary code in the builder pod context. This issue has been patched in version 1.23.0.

Fission 操作系统命令注入漏洞

Fission是Fission开源的一个基于Kubernetes的函数部署框架。 Fission 1.23.0之前版本存在操作系统命令注入漏洞，该漏洞源于构建器将Environment.spec.builder.command直接传递给exec.Command，未验证可执行路径或参数，允许用户创建或更新Environment CRD时在构建器Pod上下文中执行任意代码。
