Detailsinfo

A vulnerability, which was classified as critical, has been found in conda-build up to 25.2.x. Affected by this issue is an unknown code of the component conda-index. The manipulation with an unknown input leads to a reliance on uncontrolled component vulnerability. Using CWE to declare the problem leads to CWE-1357. The product is built from multiple separate components, but it uses a component that is not sufficiently trusted to meet expectations for security, reliability, updateability, and maintainability. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Conda-build contains commands and tools to build conda packages. Prior to version 25.3.0, the pyproject.toml lists conda-index as a Python dependency. This package is not published in PyPI. An attacker could claim this namespace and upload arbitrary (malicious) code to the package, and then exploit pip install commands by injecting the malicious dependency in the solve. This issue has been fixed in version 25.3.0. A workaround involves using --no-deps for pip install-ing the project from the repository.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-32800 since 04/10/2025. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

Upgrading to version 25.3.0 eliminates this vulnerability. Applying the patch f5a6aeef0d5d6940b8c2a88796910dc7476a62bb is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
