Moderate severity GitHub Reviewed Published Feb 18, 2019 to the GitHub Advisory Database • Updated Sep 13, 2023

Package

npm backbone (npm)

Affected versions

< 0.5.0

Patched versions

0.5.0

Description

Affected versions of backbone are vulnerable to cross-site scripting when users are allowed to supply input to the Model#Escape function, and the output is then written to the DOM.

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.
