What is CVE-2025-32798?

Conda-Build, a tool for building conda packages, is susceptible to arbitrary code execution due to unsafe evaluation of recipe selectors in meta.yaml files before version 25.4.0. The use of the eval function lacks proper input sanitization, allowing potentially malicious code to be executed during the package build process. This exposes the build environment to unauthorized commands and file operations, undermining the security of the packaging system. Users are encouraged to upgrade to version 25.4.0 or later to mitigate this risk.

Affected Version(s)

conda-build < 25.4.0
