Cross-Site Scripting in react

ÉLEVÉEGHSA-hg79-j56m-fxgv · Published 04/09/2020 · updated 01/10/2021

Package	Affected versions	Patched versions
react npm	`≥ 0.0.1, < 0.14.0`	`0.14.0`

Description

Versions of react prior to 0.14.0 are vulnerable to Cross-Site Scripting (XSS). The package's createElement function fails to properly validate its input object, allowing attackers to execute arbitrary JavaScript in a victim's browser.

Recommendation

Upgrade to version 0.14.0 or later.
