AngularJS Cross-site Scripting due to failure to sanitize `xlink.href` attributes

Moderate severity GitHub Reviewed Published Feb 14, 2020 to the GitHub Advisory Database • Updated Jan 27, 2023

Package

npm angular (npm)

Affected versions

< 1.5.0-beta.1

Patched versions

1.5.0-beta.1

Description

Versions of angular prior to 1.5.0-beta.1 are vulnerable to Cross-Site Scripting. The package fails to sanitize xlink:href attributes, which may allow attackers to execute arbitrary JavaScript in a victim's browser if the value is user-controlled.

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.
