Conda-build Allows Arbitrary Code Execution via Malicious Recipe Selectors

Conda-build contains commands and tools to build conda packages. Prior to version 25.4.0, the conda-build recipe processing logic has been found to be vulnerable to arbitrary code execution due to unsafe evaluation of recipe selectors. Currently, conda-build uses the eval function to process embedded selectors in meta.yaml files. This approach evaluates user-defined expressions without proper sanitization, which allows arbitrary code to be executed during the build process. As a result, the integrity of the build environment is compromised, and unauthorized commands or file operations may be performed. The vulnerability stems from the inherent risk of using eval() on untrusted input in a context intended to control dynamic build configurations. By directly interpreting selector expressions, conda-build creates a potential execution pathway for malicious code, violating security assumptions. This issue has been patched in version 25.4.0.

Conda-build 代码注入漏洞

Conda-build是Conda开源的一个用于构建conda包的命令和工具。 Conda-build 25.4.0之前版本存在代码注入漏洞，该漏洞源于对recipe selectors的不安全评估，可能导致任意代码执行。
