XSS Vulnerability in Markdown Editor
Impact
InvenTree uses EasyMDE 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
- Enforce cleaning of all data uploaded to the database via the API - #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.
