Moderate severity GitHub Reviewed Published Feb 10, 2022 to the GitHub Advisory Database • Updated Jan 29, 2023

Package

npm froala-editor (npm)

Affected versions

< 3.2.3

Description

Froala WYSIWYG HTML Editor is a lightweight WYSIWYG HTML Editor written in JavaScript that enables rich text editing capabilities for web applications. A DOM-based cross-site scripting (XSS) vulnerability exists in versions before 3.2.3 because HTML code in the editor is not correctly sanitized when inserted into the DOM. This allows an attacker that can control the editor content to execute arbitrary JavaScript in the context of the victim’s session.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
