Description

This security bulletin contains information about 1 security vulnerability.

1) Cross-site scripting (CVE-ID: CVE-2026-27142)

The vulnerability allows a remote attacker to execute arbitrary script code in a victim's browser via cross-site scripting (XSS).

The vulnerability exists due to improper output neutralization in html/template when inserting URLs into the content attribute of HTML meta tags with an http-equiv="refresh" attribute. A remote attacker can craft a URL that is not properly escaped, leading to script execution when the page is rendered.

Exploitation requires user interaction, as the victim must load the malicious page. This vulnerability affects applications using the html/template package to generate such meta tags.
