CSRF issue on preview pages in Bolt CMS

High severity GitHub Reviewed Published Jun 8, 2020 in bolt/bolt • Updated Jan 28, 2023

Package

composer bolt/bolt (Composer)

Affected versions

< 3.7.1

Patched versions

3.7.1

Description

Impact

Bolt CMS lacked CSRF protection in the preview generating endpoint. Previews are intended to be generated by the admins, developers, chief-editors, and editors, who are authorized to create content in the application. But due to lack of proper CSRF protection, unauthorized users could generate a preview.

Patches

This has been fixed in Bolt 3.7.1

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.
