AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions: Weluka Lite plugin for WordPress versions up to, and including, 1.0.3

Description: The issue is related to Stored Cross-Site Scripting via the plugin's 'weluka-map' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations: For versions up to, and including, 1.0.3, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'weluka-map' shortcode. As a temporary workaround, consider restricting access to the 'weluka-map' shortcode for users with contributor-level access and above until a patch is available.
