Administrators should monitor the vendor's advisory channels for updates. Until a patch is available, limit administrator access to trusted users and consider enabling unfiltered_html if feasible. Multi-site installations should be especially cautious. No vendor advisory states that no action is required or that the issue is already mitigated.
Description
The TWW Protein Calculator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Header' setting in all versions up to, and including, 1.0.24 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, 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.
