AI-suggested
1. Upgrade conda-forge-ci-setup-feedstock to version 4.15.0 or later immediately to apply the fix. 2. Restrict write access to CI recipe directories and environment variables such as RECIPE_DIR to trusted personnel and automated systems only. 3. Implement strict code review and validation processes for any changes to meta.yaml or other build recipe files to detect and prevent injection attempts. 4. Use isolated and ephemeral build environments to limit the impact of any potential code execution during builds. 5. Employ runtime monitoring and logging within CI pipelines to detect anomalous script execution or unexpected environment variable modifications. 6. Consider integrating static analysis or linting tools that can flag unsafe usage of eval or suspicious version strings in build recipes. 7. Educate developers and DevOps teams about the risks of eval injection and secure handling of build metadata.
Description
conda-forge-ci-setup is a package installed by conda-forge each time a build is run on CI. The conda-forge-ci-setup-feedstock setup script is vulnerable due to the unsafe use of the eval function when parsing version information from a custom-formatted meta.yaml file. An attacker controlling meta.yaml can inject malicious code into the version assignment, which is executed during file processing, leading to arbitrary code execution. Exploitation requires an attacker to modify the recipe file by manipulating the RECIPE_DIR variable and introducing a malicious meta.yaml file. While this is more feasible in CI/CD pipelines, it is uncommon in typical environments, reducing overall risk. This vulnerability is fixed in 4.15.0.
