CVE-2022-0282Public exploitNetwork attack vector

Stored script execution via unescaped comment body

Published Jan 20, 2022 · Updated Aug 2, 2024

Stored cross-site scripting in Microweber before 1.2.11 allows remote attackers to inject script through a crafted comment body. The comments data path returned comment_body without HTML encoding, and the admin comment template printed that value directly into a div and textarea. The script executes when an administrator opens the affected comment view, enabling browser-context actions under that user's session.
