CVE-2022-35509Network attack vector

Stored script execution via unsanitized contribution titles

Published Aug 9, 2022 · Updated Jun 23, 2026

Stored XSS in EyouCMS 1.5.8 allows remote attackers to execute arbitrary scripts through the foreground-contribution title parameter. The contribution workflow stores attacker-supplied title content without neutralizing script-related HTML before rendering it in a browser. Exploitation requires another user to view the saved contribution, allowing the script to run in that user's browser context and access sensitive page information.
