CVE-2023-32961Network attack vector

Reflected XSS via unescaped OAuth parameters

Published Jun 12, 2023 · Updated Apr 28, 2026

Reflected XSS in Katie Seaborn Zotpress 7.3.3 and earlier allows remote attackers to execute scripts via crafted OAuth parameters. The optional OAuth request-token handler in lib/admin/admin.accounts.oauth.php reflects oauth_token and return_uri query parameters without adequate sanitization or output escaping. Exploitation requires OAuth to be enabled and a privileged user to follow a crafted link; injected script then runs in that user's WordPress origin.
