Vulnerability Details

CVEID:CVE-2021-22959
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling, caused by an error related to a space in headers. A remote attacker could send a specially-crafted request with a space (SP) right after the header name before the colon to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/211168 for the current score.
