Upgrade drupal/core to 7.65.0
drupal/core fixed: 8.5.14 
Upgrade drupal/core to 8.5.14
drupal/core fixed: 8.6.13 
Upgrade drupal/core to 8.6.13
drupal/drupal fixed: 7.65.0 
Upgrade drupal/drupal to 7.65.0
drupal/drupal fixed: 8.5.14 
Upgrade drupal/drupal to 8.5.14
drupal/drupal fixed: 8.6.13 
Upgrade drupal/drupal to 8.6.13
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for drupal/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-6341, inspect your project dependencies for Drupal/core:

inspect dependencies for drupal/core

Analyze the terminal output to locate any version of Drupal/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.65.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

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 Drupal/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

In Drupal 7 versions prior to 7.65; Drupal 8.6 versions prior to 8.6.13;Drupal 8.5 versions prior to 8.5.14. Under certain circumstances the File `module/subsystem` allows a malicious user to upload a file that can trigger a cross-site scripting (XSS) vulnerability.
