verbb/formie Server-Side Template Injection for variable-enabled settings

Moderate severity GitHub Reviewed Published May 18, 2024 in verbb/formie • Updated May 20, 2024

Package

composer verbb/formie (Composer)

Affected versions

< 2.1.6

Patched versions

2.1.6

Description

Impact

Users with access to a form's settings can include malicious Twig code into fields that support Twig. These might be the Submission Title or the Success Message. This code will then be executed upon creating a submission, or rendering the text.

This is listed as low-medium severity due to requiring control panel access to edit a form's settings.

Patches

This has been fixed in Formie 2.1.6. Users should ensure they are running at least this version.

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.
