How to Fix CVE-2025-3044

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

llama-index-readers-papers fixed: 0.3.1 
pip install llama-index-readers-papers>=0.3.1
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 llama-index-readers-papers

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-3044, inspect your installed packages using pip:

pip show llama-index-readers-papers

Analyze the terminal output to locate any version of Llama index readers papers in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.1), your application is affected.

Note: The pip show llama-index-readers-papers command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-440: Expected Behavior Violation, where a feature, api, or function does not perform according to its specification. In Llama index readers papers, 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 the ArxivReader class of the run-llama/llama_index repository allows for MD5 hash collisions when generating filenames for downloaded papers. This can lead to data loss as papers with identical titles but different contents may overwrite each other, preventing some papers from being processed for AI model training. The issue is resolved in llama-index-readers-papers version 0.3.1 (in llama-index 0.12.28).
