CVE-2023-30498Network attack vector

Reflected XSS via unescaped view and page parameters

Published Aug 15, 2023 · Updated Apr 28, 2026

Reflected XSS in Constantin Boiangiu Vimeotheque 2.2.1 and earlier allows remote attackers to run script via crafted requests. The view and page request parameters reach an administrative-page response without sufficient input sanitization or output escaping, causing attacker-controlled markup to be reflected. Exploitation requires a user to follow a crafted link, after which the script executes in that user's browser context and can act with that session's privileges.
