Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Liquid Web / StellarWP GiveWP allows DOM-Based XSS.

This issue affects GiveWP: from n/a through 4.14.5.

AnalysisAI

DOM-based cross-site scripting in the GiveWP WordPress donation plugin (versions up to and including 4.14.5) allows remote attackers to execute arbitrary JavaScript in a victim's browser session after the victim interacts with an attacker-supplied link or page element. The flaw carries a CVSS 7.1 score driven by changed scope (S:C), meaning impact extends beyond the vulnerable component into the surrounding WordPress site context. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

Technical ContextAI

GiveWP is a widely deployed WordPress donation/fundraising plugin maintained by Liquid Web / StellarWP, identified by CPE cpe:2.3:a:liquid_web_/_stellarwp:givewp. The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), specifically a DOM-based variant where untrusted input flows through client-side JavaScript sinks (e.g., innerHTML, document.write, jQuery .html()) without proper neutralization. Unlike reflected or stored XSS, DOM-based XSS executes entirely in the browser when client-side script reads attacker-controllable values (URL fragments, query parameters, postMessage data) and injects them into the DOM, meaning the payload may never appear in server logs.

RemediationAI

Upgrade GiveWP to a version newer than 4.14.5 once StellarWP publishes a fixed release; consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/give/vulnerability/wordpress-givewp-plugin-4-14-5-cross-site-scripting-xss-vulnerability and the StellarWP changelog for the exact patched build, as no vendor-released patched version was independently confirmed in the available data. As compensating controls until a patch is applied, deploy a strict Content-Security-Policy header that disables inline script and restricts script-src to trusted origins (note this can break legitimate plugin functionality and must be tested), enable a WordPress-aware WAF such as Patchstack, Wordfence, or Sucuri with virtual-patching for this CVE, restrict /wp-admin access by IP to limit exposure of authenticated administrators to malicious links, and instruct site administrators to avoid clicking GiveWP-related URLs from untrusted sources until the upgrade is completed.
