CVE-2026-5077
CWE-79Published: May 2, 2026· Updated: May 5, 2026
Official Description
The Total theme for WordPress is vulnerable to Stored Cross-Site Scripting via post titles in versions up to, and including, 2.2.1 due to insufficient output escaping when rendering the_title() inside HTML attribute context in the home blog section template. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the malicious post to be published and displayed with a featured image in the Home Page blog section.
Technical Analysis
CVE-2026-5077 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
