CVE-2025-12588 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the USB Qr Code Scanner For Woocommerce plugin for WordPress, affecting all versions up to and including 1.0.0. The root cause is the absence of nonce validation on the plugin's settings page, which is a security mechanism designed to verify the legitimacy of requests and prevent unauthorized actions. Without this protection, an attacker can craft a malicious web request that, when executed by an authenticated administrator (e.g., by clicking a link or visiting a malicious webpage), causes the plugin's settings to be altered without the administrator's consent. This type of attack exploits the trust a web application places in the user's browser and session. The vulnerability does not require the attacker to be authenticated, but it does require user interaction from an administrator-level user. The impact is primarily on the integrity of the plugin's configuration, as unauthorized changes could disrupt functionality or enable further attacks. Confidentiality and availability are not directly impacted. The CVSS v3.1 base score is 4.3, reflecting a medium severity level due to the ease of exploitation (no privileges required, low attack complexity) but limited impact scope. No patches or fixes are currently linked, and no known exploits have been reported in the wild. The vulnerability was published on November 11, 2025, and assigned by Wordfence.

For European organizations using WooCommerce with the USB Qr Code Scanner plugin, this vulnerability poses a risk of unauthorized configuration changes that could degrade the integrity of e-commerce operations. Attackers could manipulate plugin settings to disrupt scanning functionality, potentially causing operational delays or errors in order processing. While the vulnerability does not directly expose sensitive data or cause service outages, altered settings might be leveraged as a foothold for further attacks or to introduce malicious behavior. This risk is particularly relevant for organizations relying on automated QR code scanning for inventory or sales processes. The requirement for administrator interaction limits the attack vector but does not eliminate risk, especially in environments where administrators may be targeted via phishing or social engineering. The medium severity suggests moderate urgency in addressing the issue to maintain operational integrity and prevent potential escalation.

1. Immediately update the USB Qr Code Scanner For Woocommerce plugin once a patch is released that includes nonce validation on the settings page. 2. Until a patch is available, restrict administrative access to trusted networks and users to reduce the risk of CSRF exploitation. 3. Educate administrators about the risks of clicking on unsolicited links or visiting untrusted websites while logged into the WordPress admin panel. 4. Implement Content Security Policy (CSP) headers and SameSite cookie attributes to help mitigate CSRF risks at the browser level. 5. Use security plugins or web application firewalls (WAFs) that can detect and block suspicious POST requests targeting the plugin's settings endpoints. 6. Regularly audit plugin configurations and monitor logs for unexpected changes to detect potential exploitation attempts early. 7. Consider disabling or removing the plugin if it is not essential to reduce the attack surface.
