6.3.1- Upgrade drupal/webform to this version or later
Description
The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data.
The module does not sufficiently restrict access to raw webform source editing when the Webform UI module is not enabled. This could allow a user with webform creation or editing permissions to enter source configuration that is rendered unsafely.
This vulnerability is mitigated by the fact that an attacker must have permission to create or edit webforms.
Affected versions
Packagist:https://packages.drupal.org/8
| Package | Vulnerable | Fixed in |
|---|---|---|
| drupal/webform | < 6.2.12>= 6.3.0, < 6.3.1 |
6.2.126.3.1 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
drupal/webform Packagist:https://packages.drupal.org/8 → 6.3.1

Weakness
CWE-267: Privilege Defined With Unsafe Actions
A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.
How to prevent it
- Architecture and Design, Operation: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Architecture and Design, Operation: Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
