CVE-2026-2499Network attack vector

Administrator stored XSS via unescaped logo path

Published Feb 26, 2026 · Updated Feb 26, 2026

Stored XSS in Custom Logo 2.2 and earlier allows remote authenticated users to inject scripts through the logo-path setting. The plugin stores the administrator-supplied logo-path setting and renders it into page output without sufficient input sanitization or output escaping. Administrator privileges are required, and exposure is limited to multisite installations or sites where unfiltered_html is disabled; injected scripts execute when a user opens an affected page.
