Recommendation: Plan a near-term fix — a public PoC already exists.

The Shariff for WordPress Shariff for WordPress plugin through 1.0.11 does not sanitize or escape the shariff_infourl setting before outputting it in the frontend HTML via the generateshariff() function, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
