CVE-2022-44630: YITH WooCommerce Product Slider Carousel CSRF Vulnerability

Technical summary

This CSRF vulnerability (CWE-352) in YITH WooCommerce Product Slider Carousel allows an unauthenticated attacker to execute arbitrary actions in the context of an authenticated user session. The plugin fails to implement adequate CSRF token validation on state-changing operations, allowing POST requests to be forged from external sites. The attack requires user interaction (the victim must visit an attacker-controlled page while logged in) and does not affect the confidentiality or availability of the WordPress instance directly, but can compromise the integrity of carousel content and settings.

Business impact

WooCommerce store administrators using this plugin are at risk of unauthorized modification of product carousel configurations, potentially disrupting customer experience or leading to defacement. In a multi-user environment, an attacker could alter promotional carousels, product display logic, or associated metadata without administrative knowledge, eroding trust in the storefront and potentially affecting sales presentation. The impact is limited to settings integrity rather than data exfiltration or service disruption.

Affected systems

WordPress installations running the YITH WooCommerce Product Slider Carousel plugin in version 1.16.0 or earlier are affected. The vulnerability requires the victim to be an authenticated administrator or user with plugin settings access. Impact scope is limited to WooCommerce environments where this specific plugin is active.

Exploitability

Exploitability is moderate. An attacker must craft a malicious webpage or inject JavaScript into a site the target admin visits while logged into WordPress. No special network access or authentication by the attacker is required, but the attack depends on social engineering or compromise of a trusted site to deliver the malicious request. No public exploit code is known to exist, and the issue has not been flagged as actively exploited in the wild.

Remediation

Update the YITH WooCommerce Product Slider Carousel plugin to a patched version released after 1.16.0. Verify the latest security update directly from the YITH plugin repository or the vendor's security advisory. Additionally, implement WordPress security best practices: enforce strong administrator passwords, use two-factor authentication, and consider restricting plugin access to trusted users only.

Patch guidance

Check the official YITH plugin repository or vendor advisory for version 1.16.1 or later. Apply the update through the WordPress admin dashboard (Plugins > Installed Plugins) or via command line if your environment supports it. Test the update in a staging environment first to ensure carousel functionality remains intact and no display regressions occur. Verify that no custom carousel configurations are lost during the upgrade.

Detection guidance

Monitor WordPress admin access logs for unusual activity from unfamiliar IP addresses or user agents coinciding with unexpected carousel setting changes. Review plugin audit logs if available. Implement Content Security Policy (CSP) headers to restrict cross-origin form submissions. Use WordPress security scanning tools to detect outdated plugin versions. Watch for POST requests to plugin action handlers lacking valid nonce verification in your web application firewall logs.

Why prioritize this

Although the CVSS score is medium (4.6), this vulnerability warrants prompt attention because it directly targets administrative functions on customer-facing ecommerce platforms. Plugin vulnerabilities affecting WooCommerce are high-value targets for attackers seeking to manipulate product display and customer experience. Prioritize patching within 30 days, especially for stores handling high transaction volumes or sensitive promotional content.

Risk score, explained

The CVSS 3.1 score of 4.6 reflects limited scope: the attack requires user interaction, affects only authenticated sessions, and produces no impact on confidentiality or availability (only integrity of plugin settings). However, the real-world risk is amplified by the ubiquity of WooCommerce and the sensitivity of administrative access, warranting a faster patching timeline than the base score alone suggests.
