How to Fix CVE-2025-3046

To remediate this vulnerability, upgrade all affected Llama index readers obsidian 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-obsidian fixed: 0.5.1 
pip install llama-index-readers-obsidian>=0.5.1
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-obsidian

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-3046, inspect your installed packages using pip:

pip show llama-index-readers-obsidian

Analyze the terminal output to locate any version of Llama index readers obsidian in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Llama index readers obsidian, 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 `ObsidianReader` class in LlamaIndex Readers Integration: Obsidian before version 0.5.1 from the run-llama/llama_index repository (versions 0.12.23 to 0.12.28) allows for arbitrary file read through symbolic links. The `ObsidianReader` fails to resolve symlinks to their real paths and does not validate whether the resolved paths lie within the intended directory. This flaw enables attackers to place symlinks pointing to files outside the vault directory, which are then processed as valid Markdown files, potentially exposing sensitive information.
