GiveWP Plugin CSRF and Stored XSS Vulnerabilities

Stored Cross-Site Scripting in GiveWP versions up to and including 4.16.0 allows authenticated attackers with author-level WordPress access to inject persistent JavaScript payloads via the 'block_id' attribute of the 'givewp_campaign_comments' shortcode. The flaw originates in two code paths - CampaignCommentsShortcode::parseAttributes() and BlockRenderController::render() - where the blockId value is interpolated directly into a single-quoted HTML attribute without WordPress's esc_attr() sanitization function. Any visitor loading an injected page will have the malicious script execute in their browser context. No active exploitation is confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis.

Cross-Site Request Forgery in GiveWP - Donation Plugin and Fundraising Platform (versions up to and including 4.15.3) allows unauthenticated remote attackers to disable donation email notifications by tricking a logged-in administrator into clicking a crafted link. The root cause is absent nonce validation in the give_set_notification_status_handler() AJAX handler, permitting forged state-changing requests. No public exploit code has been identified and this CVE is not listed in the CISA KEV catalog; however, the integrity impact - silently disabling donation notifications - could cause operational blind spots for nonprofit or fundraising site operators.
