Stellarwp GiveWP – Donation Plugin and Fundraising Platform vulnerabilities

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.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'give_form' shortcode in all versions up to, and including, 4.14.4. This is due to insufficient input sanitization and output escaping on the continue_button_title and display_style shortcode attributes, which are passed through sanitize_text_field() but not properly escaped when output in HTML data attributes. 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.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'twitter_message' Sequoia Template Setting in all versions up to, and including, 4.16.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with give worker-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected script executes specifically when a donor clicks the Share on Twitter button on the Sequoia donation confirmation view, as that is when the unescaped twitter_message value is evaluated inside the JavaScript template literal.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sequoia[introduction][image]' parameter in all versions up to, and including, 4.16.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Give Worker-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'block_id' (and other) shortcode attributes of the 'givewp_campaign_comments' shortcode in versions up to, and including, 4.16.0. This is due to insufficient input sanitization and output escaping on user supplied attributes in CampaignCommentsShortcode::parseAttributes() and BlockRenderController::render(), where the blockId value is interpolated directly into a single-quoted HTML attribute without esc_attr(). This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The GiveWP plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.15.3 This is due to missing nonce validation on the give_set_notification_status_handler() function. This makes it possible for unauthenticated attackers to disable donation email notifications via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter in all versions up to, and including, 4.13.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Avatars must be enabled in the WordPress install in order to exploit the vulnerability.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `registerAssociateFormsWithCampaign` function in all versions up to, and including, 4.10.0. This makes it possible for unauthenticated attackers to associate any donation forms with any campaign.

The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 4.10.0 via the 'registerGetForm', 'registerGetForms', 'registerGetCampaign' and 'registerGetCampaigns' functions due to a missing capability check. This makes it possible for unauthenticated attackers to extract data from private and draft donation forms, as well as archived campaigns.
