CVE-2026-13246: Stellarwp Givewp – Donation Plugin And Fundraising Platform

Medium severity, CVSS 6.4. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Stellarwp Givewp – Donation Plugin And Fundraising Platform: up to and including 4.16.0
