How to Fix CVE-2024-41950

To remediate this vulnerability, upgrade all affected Haystack ai dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

haystack-ai fixed: 2.3.1 
pip install haystack-ai>=2.3.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show haystack-ai

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-41950, inspect your installed packages using pip:

pip show haystack-ai

Analyze the terminal output to locate any version of Haystack ai in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.1), your application is affected.

Note: The pip show haystack-ai command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1336: Improper Neutralization of Special Elements Used in a Template Engine, where the product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine. In Haystack ai, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Haystack clients that let their users create and run Pipelines from scratch are vulnerable to remote code executions. Certain Components in Haystack use Jinja2 templates, if anyone can create and render that template on the client machine they run any code. ### Patches The problem has been fixed with PRs deepset-ai/haystack#8095 and deepset-ai/haystack#8096. Both have been released with Haystack `2.3.1`. ### Workarounds Prevent users from running the affected Components, or only let users use preselected templates. ### References The list of impacted Components can be found in the release notes for `2.3.1`. https://github.com/deepset-ai/haystack/releases/tag/v2.3.1
