Description

The Klaviyo WordPress plugin before 3.0.10 does not sanitize and escape some of its settings, 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).

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown Klaviyo — Before 3.0.10
  • klaviyo klavio — Before 3.0.10
