CVE-2026-29106 Details
Description
SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, the value of the return_id request parameter is copied into the value of an HTML tag attribute which is an event handler and is encapsulated in double quotation marks. Versions 7.15.1 and 8.9.3 patch the issue. Users should also use a Content Security Policy (CSP) header to completely mitigate XSS.
A cross-site scripting (XSS) vulnerability has been identified in SuiteCRM versions prior to 7.15.1 and 8.9.3. The issue arises because the return_id request parameter is directly copied into an HTML tag attribute as an event handler, enclosed in double quotation marks. This vulnerability allows an attacker with admin privileges to inject advanced malicious payloads, potentially chaining them with other attack vectors like Cross-Site Request Forgery (CSRF) to act on behalf of the victim. Exploitation could also involve redirecting victims to a malicious website, defacing page content, or, in cases of improper httpOnly cookie flag management, stealing session cookies for session hijacking.
Users are advised to upgrade to SuiteCRM versions 7.15.1 or 8.9.3. Additionally, implementing a Content Security Policy (CSP) header can help mitigate XSS vulnerabilities.
