Is this vulnerability remotely exploitable?

Yes. An attacker can remotely exploit the issue by sending or embedding a specially crafted Movary URL containing a malicious `categoryCreated` value. When a victim loads that URL, the script can execute in their browser.

Does exploitation require authentication?

The attacker does not need to be authenticated to craft a malicious URL. However, the impact is significantly higher when the victim is logged into Movary, since injected scripts then run with the victim's session privileges.

What is the safest general fix pattern?

The most robust fix is to enforce context-aware output encoding for all user-controlled data rendered in pages, combined with strict server-side validation and normalization of query parameters. Avoid any direct insertion of raw user input into HTML or script contexts.
