Name of the Vulnerable Software and Affected Versions WP Last Modified Info plugin for WordPress versions up to, and including, 1.9.0

Description The issue is related to Stored Cross-Site Scripting via the template attribute of the lmt-post-modified-info shortcode. This is due to insufficient input sanitization and output escaping, making it possible for authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages. These scripts will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 1.9.0, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the lmt-post-modified-info shortcode to minimize the risk of exploitation. Avoid using the template attribute in the affected shortcode until the issue is resolved.
