Stored XSS via missing nonce validation
Published Nov 13, 2023 · Updated Apr 28, 2026
CSRF in tagDiv Composer before 4.4 allows remote attackers to inject stored scripts through an administrator's forged request. The affected request handler performs missing or incorrect nonce validation before accepting script-bearing input; the function is undisclosed. Exploitation requires an authenticated administrator to visit a crafted page or activate a malicious link, after which injected scripts execute in site visitors' browsers.
