Cross site scripting
CVE: CVE-2023-3978
Component: golang.org/x/net/html
CWE: CWE-79
Severity: Moderate
CVSS v3: 6.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Release date: 2023-08-02T00:00:00+00:00

A flaw was found in the Golang HTML package where it is vulnerable to Cross-site scripting caused by the improper validation of user-supplied input. A remote attacker could exploit this vulnerability using a specially crafted URL to execute a script in a victim's web browser within the security context of the hosting website once the URL is clicked. The flaw allows an attacker to steal the victim's cookie-based authentication credentials.
