CVE-2025-48093Network attack vector

Script execution via redirect_to reflection

Published Oct 22, 2025 · Updated Oct 22, 2025

Reflected XSS in Calvaweb Password only login 0.2 and earlier allows remote attackers to run scripts through a crafted login-form URL. The plugin's custom form reflects the redirect_to query-string input into page output, but the publisher has not disclosed the exact output statement or escaping failure. Exploitation requires a victim to visit the crafted URL on a site that exposes the custom form; the script runs in that site's origin.
