AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Stored XSS requires a victim to load the injected page for impact, making UI:R more accurate than the provided UI:N; PR:L reflects the mandatory Give Worker role.

Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Stored Cross-Site Scripting in GiveWP (WordPress Donation Plugin and Fundraising Platform) versions up to and including 4.16.1 allows authenticated attackers holding the Give Worker role or above to inject persistent malicious scripts via the Sequoia form template's introduction image parameter. The CVSS Scope:Changed rating reflects that injected payloads execute in the security context of any victim browser that loads the affected donation page, enabling session hijacking or credential theft from site visitors and administrators alike. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Technical ContextAI
GiveWP is a widely-used WordPress plugin providing donation form management, including a Sequoia form template layout. The vulnerable parameter is sequoia[introduction][image], processed through includes/admin/forms/class-metabox-form-data.php (L1180) and includes/formatting.php (L758), and rendered via src/Views/Form/Templates/Sequoia/sections/introduction.php (L33) and src/Views/Form/Templates/Sequoia/Sequoia.php (L459) - all confirmed in NVD source references for tags 4.14.6 and 4.16.0. CWE-79 (Improper Neutralization of Input During Web Page Generation) identifies the root cause: the image field value is stored without adequate sanitization and later rendered into HTML output without proper escaping, allowing injected script tags to survive round-trip storage and page rendering. The Scope:Changed (S:C) metric in the CVSS vector reflects the cross-boundary nature of XSS - the attacker writes to the server but the code executes in victims' browsers.
RemediationAI
Update the GiveWP plugin to a version above 4.16.1 - the exact patched release version is not confirmed in the available intelligence data, so administrators should consult the official WordPress plugin repository changelog and the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/ee18552b-2814-4598-9b7b-7c919d6d644e to identify the confirmed fix release before upgrading. As a compensating control while patching is pending, audit and restrict Give Worker role assignments to only fully trusted internal staff, removing the role from volunteers or external campaign managers - this eliminates the attacker's required privilege level and is the highest-value short-term mitigation. If the Sequoia form template is not actively in use, switching all donation forms to an alternate GiveWP template removes the vulnerable code path entirely without functional loss for most sites. Note that restricting roles is a people-process control and does not patch the underlying code defect.
