CVE-2023-3088Public exploitNetwork attack vector

Stored XSS via unescaped email log rendering

Published Jul 12, 2023 · Updated Apr 8, 2026

Stored cross-site scripting in WPVibes WP Mail Log 1.1.1 and earlier allows remote attackers to execute scripts through logged email content. The administrative email log view stores attacker-influenced email content and renders it without sufficient sanitization or output escaping. Exploitation requires a site feature that lets an unauthenticated visitor influence an outgoing email and an authenticated user to open the resulting log entry, where the script runs in that viewer's browser.
