CVE-2026-25143— melange 操作系统命令注入漏洞

melange affected by potential host command execution via license-check YAML mode patch pipeline

melange allows users to build apk packages using declarative pipelines. From version 0.10.0 to before 0.40.3, an attacker who can influence inputs to the patch pipeline could execute arbitrary shell commands on the build host. The patch pipeline in pkg/build/pipelines/patch.yaml embeds input-derived values (series paths, patch filenames, and numeric parameters) into shell scripts without proper quoting or validation, allowing shell metacharacters to break out of their intended context. The vulnerability affects the built-in patch pipeline which can be invoked through melange build and melange license-check operations. An attacker who can control patch-related inputs (e.g., through pull request-driven CI, build-as-a-service, or by influencing melange configurations) can inject shell metacharacters such as backticks, command substitutions $(…), semicolons, pipes, or redirections to execute arbitrary commands with the privileges of the melange build process. This issue has been patched in version 0.40.3.

melange 操作系统命令注入漏洞

melange是Chainguard开源的一个从源代码构建APK的软件。 melange 0.10.0版本至0.40.3之前版本存在操作系统命令注入漏洞，该漏洞源于补丁管道将输入派生的值嵌入shell脚本时未正确引用或验证，可能导致执行任意shell命令。
