CVE-2024-6864

WP Last Modified Info <= 1.9.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via lmt-post-modified-info Shortcode

6.4 Medium

The WP Last Modified Info plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘template’ attribute of the lmt-post-modified-info shortcode in all versions up to, and including, 1.9.0 due to insufficient input sanitization and output escaping. 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.
