- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

## Affected

- stellarwp GiveWP – Donation Plugin and Fundraising Platform: through 4.17.0

## Description

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `givewp_campaign_grid` shortcode in versions up to, and including, 4.17.0 This is due to insufficient input sanitization and output escaping on user supplied shortcode attributes (`filter_by`, `layout`, `sort_by`, `order_by`) in the CampaignGridShortcode::parseAttributes() function combined with the render template emitting `json_encode($attributes)` inside a single-quoted HTML attribute without esc_attr() — json_encode() does not escape single quotes by default, so a `'` in an attribute value breaks out of the enclosing attribute. 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.
