Official description
The Affiliate Program Suite — SliceWP Affiliates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode attributes in all versions up to, and including, 1.2.7. This is due to insufficient input sanitization and output escaping on user-supplied attributes in the 'slicewp_affiliate_url' shortcode. This makes it possible for 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.
