How to Fix CVE-2024-10940

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

langchain-core fixed: 0.1.53 
pip install langchain-core>=0.1.53
langchain-core fixed: 0.2.43 
pip install langchain-core>=0.2.43
langchain-core fixed: 0.3.15 
pip install langchain-core>=0.3.15
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 langchain-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-10940, inspect your installed packages using pip:

pip show langchain-core

Analyze the terminal output to locate any version of Langchain core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.53), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere, where the product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does. In Langchain core, 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

A vulnerability in langchain-core versions >=0.1.17,<0.1.53, >=0.2.0,<0.2.43, and >=0.3.0,<0.3.15 allows unauthorized users to read arbitrary files from the host file system. The issue arises from the ability to create langchain_core.prompts.ImagePromptTemplate's (and by extension langchain_core.prompts.ChatPromptTemplate's) with input variables that can read any user-specified path from the server file system. If the outputs of these prompt templates are exposed to the user, either directly or through downstream model outputs, it can lead to the exposure of sensitive information.
