CVE-2020-7656
MEDIUM6.1EPSS 0.89%Cross-Site Scripting in jquery
Published: 5/20/2020Modified: 3/13/2026
Also known as:GHSA-q4m3-2j7h-f7xw
Description
Versions of `jquery` prior to 1.9.0 are vulnerable to Cross-Site Scripting. The load method fails to recognize and remove `<script>` HTML tags that contain a whitespace character, i.e: `</script >`, which results in the enclosed script logic to be executed. This allows attackers to execute arbitrary JavaScript in a victim's browser. ## Recommendation Upgrade to version 1.9.0 or later.
Affected packages (4)
- Maven/org.webjars.npm:jquery>= 1.2.1, < 1.9.0
- npm/jquery>= 1.2.1, < 1.9.0
