CVE-2026-13246Network attack vector

Stored XSS via unescaped campaign-comment attributes

Published Jul 1, 2026 · Updated Jul 1, 2026

Stored XSS in GiveWP 4.16.0 and earlier allows remote authenticated users to run scripts through campaign-comments shortcode attributes. CampaignCommentsShortcode::parseAttributes passes block_id into BlockRenderController::render, which places it in a single-quoted HTML attribute without escaping. Author-level access is required; injected scripts execute in the browser of each user who opens the affected page and can act with that user's session.
