DescriptionCVE.org

Cross-Site Request Forgery (CSRF) vulnerability in ThemeGoods Grand Car Rental grandcarrental allows Cross Site Request Forgery.This issue affects Grand Car Rental: from n/a through <= 3.6.9.

AnalysisAI

Cross-site request forgery (CSRF) in ThemeGoods Grand Car Rental WordPress theme versions up to 3.6.9 allows authenticated attackers to perform unauthorized actions on behalf of users through malicious web pages. The vulnerability requires user interaction (UI:R) and affects confidentiality, integrity, and availability with low impact. EPSS exploitation probability is 0.01% (1st percentile), indicating minimal real-world exploitation likelihood despite the moderate CVSS score of 6.5.

Technical ContextAI

This is a CSRF vulnerability (CWE-352) in a WordPress theme plugin, where the application fails to implement or properly validate anti-CSRF tokens (such as WordPress nonces) on state-changing requests. The Grand Car Rental theme, delivered via WordPress plugin architecture (CPE: cpe:2.3:a:themegoods:grand_car_rental:*:*:*:*:*:*:*:*), lacks adequate protections to prevent cross-origin requests from executing actions without explicit user consent. WordPress themes are server-side template systems; this CSRF affects any functionality exposed by the theme that modifies data without token validation.

RemediationAI

Upgrade ThemeGoods Grand Car Rental theme to a version newer than 3.6.9; exact patched version not specified in available data but the advisory at Patchstack should contain the target version. As an interim workaround, site administrators can restrict theme functionality through WordPress user role and capability filtering, or disable affected features until an update is applied. Refer to the Patchstack advisory for vendor-specific guidance on patch availability and deployment.
