Cross-Site Scripting in react

Moderate severity GitHub Reviewed Published Sep 4, 2020 to the GitHub Advisory Database • Updated May 22, 2023

Package

npm react (npm)

Affected versions

>= 0.4.0, < 0.4.2
>= 0.5.0, < 0.5.2

Patched versions

0.4.2
0.5.2

Description

Affected versions of react are vulnerable to Cross-Site Scripting (XSS). The package fails to properly sanitize input used to create keys. This may allow attackers to execute arbitrary JavaScript if a key is generated from user input.

Recommendation

If you are using react 0.5.x, upgrade to version 0.5.2 or later.
If you are using react 0.4.x, upgrade to version 0.4.2 or later.

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.
