CVE-2022-0531Public exploitNetwork attack vector

Reflected XSS via unsanitized sub_page

Published Apr 11, 2022 · Updated Aug 2, 2024

Cross-site scripting in WPvivid Backup and Migration before 0.9.70 allows remote attackers to execute script in a victim's browser via a crafted sub_page parameter. The admin.php page reflects sub_page into HTML without sanitization or output escaping, allowing injected markup or script to run when the link is opened. Exploitation requires a victim to request the crafted URL while logged into WordPress; impact is browser-side code execution in the site's security context, not direct server compromise.
