How to Fix GHSA-85q9-7467-r53q

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

inventree fixed: 0.7.3 
pip install inventree>=0.7.3
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 inventree

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-85q9-7467-r53q, inspect your installed packages using pip:

pip show inventree

Analyze the terminal output to locate any version of Inventree in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.3), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Inventree, 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 InvenTree uses [EasyMDE](https://github.com/Ionaru/easy-markdown-editor) for displaying markdown text in various places (e.g. for the various "notes" fields associated with various models). By default, EasyMDE does not sanitize input data, and it is possible for malicious code to be injected into the markdown editor, and executed in the users browser. *Note: This malicious data must be first uploaded to the database by an authorized user, so the risk here is limited to trusted users* ### Solution The solution here is two-fold: - Enable data sanitization for the EasyMDE renderer - [#3205](https://github.com/inventree/InvenTree/pull/3205) - Enforce cleaning of all data uploaded to the database via the API - [#3204](https://github.com/inventree/InvenTree/pull/3204) *(This will be ready for the 0.8.0 release)* ### Patches - The issue is addressed in the 0.8.0 release - This fix was back-ported to the 0.7.x branch, applied to the 0.7.3 release ### Workarounds There is no workaround for this issue without upgrading InvenTree to the specified version. ### References - https://huntr.dev/bounties/ab296cf5-7a3e-4f49-8f63-5b35fc707f03/ ### For more information If you have any questions or comments about this advisory: * Open an issue in [github](http://github.com/inventree/inventree) * Email us at [security@inventree.org](mailto:security@inventree.org)
