CVE-2025-23998Network attack vector

Reflected XSS via unescaped request input

Published Jan 21, 2025 · Updated May 12, 2026

Reflected XSS in Rara Themes The Ultralight 1.2 and earlier allows remote attackers to inject scripts through crafted requests. Published advisories do not identify the affected parameter or template; they state only that request input is insufficiently sanitized and escaped in generated output. An attacker needs no account but must convince a user to open a crafted link, causing script execution in the site origin and access to browser-visible data or actions.
