Deeper analysis

CVE-2025-22566 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, in the ULTIMATE VIDEO GALLERY WordPress plugin by extendyourweb (ultimate-gallery). Published on 2025-03-28, it affects all versions from n/a through 1.4 inclusive, with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

The vulnerability can be exploited remotely over the network by unauthenticated attackers with low attack complexity, requiring user interaction such as visiting a maliciously crafted URL. Exploitation reflects attacker-controlled input into the web page without proper neutralization, enabling script execution in the victim's browser context due to the changed scope (S:C). This can result in low-level impacts to confidentiality, integrity, and availability, such as stealing session cookies, defacing pages, or keystroke logging within the site's domain.
