Summary

The Weekly Planner plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Risk Assessment

An attacker with administrator-level permissions can inject malicious scripts that execute in other users' browsers, potentially leading to session or data theft. The risk is limited to multi-site installations or those with unfiltered_html disabled.

Recommendation

Update the Weekly Planner plugin to a version later than 1.0 if available, or consider removing it. Additionally, verify whether unfiltered_html is enabled and restrict administrator permissions to the minimum necessary.
