PatchTheCVECVE-2025-32798: Conda-build contains commands and tools to build conda packages
CVE-2025-32798 is a critical-severity flaw (CVSS 9.8) affecting conda-build. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 execut
