CVE-2025-6053 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Zuppler Online Ordering plugin for WordPress, versions up to and including 2.1.0. The vulnerability arises due to missing or incorrect nonce validation on the 'zuppler-online-ordering-options' administrative page. Nonces are security tokens used to verify that requests to perform sensitive actions originate from legitimate users and not from unauthorized third parties. Because this validation is absent or flawed, an attacker can craft a malicious web request that, when executed by an authenticated site administrator (for example, by clicking a malicious link), causes the administrator’s browser to unknowingly perform unauthorized actions on the plugin’s settings. This can lead to unauthorized modification of plugin configurations and injection of malicious web scripts. The vulnerability does not require the attacker to be authenticated but does require user interaction from an administrator, such as clicking a link. The CVSS v3.1 base score is 6.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but user interaction needed, and a scope change indicating that the impact extends beyond the vulnerable component. The impact affects confidentiality and integrity but not availability. No known exploits are currently reported in the wild. The vulnerability is specific to WordPress sites using this plugin, which is designed for online ordering functionality, typically used by restaurants and retail businesses. The absence of a patch link suggests that a fix may not yet be publicly available or is pending release.

For European organizations, especially those in the hospitality, retail, and food service sectors that rely on WordPress websites with the Zuppler Online Ordering plugin, this vulnerability poses a significant risk. Successful exploitation could allow attackers to alter online ordering settings, potentially redirecting orders, injecting malicious scripts to steal customer data, or defacing the website. This undermines customer trust, could lead to data breaches involving personal and payment information, and disrupts business operations. Since the attack requires tricking an administrator into clicking a link, phishing campaigns targeting European businesses’ web administrators could be effective. The scope change in the vulnerability means that the attacker can affect components beyond the plugin itself, potentially compromising the broader website integrity. Given the widespread use of WordPress in Europe and the importance of e-commerce and online ordering during and post-pandemic, the impact on confidentiality and integrity could have financial and reputational consequences. However, the lack of known exploits in the wild and the medium severity score suggest the threat is moderate but should not be underestimated.

European organizations should immediately audit their WordPress installations to identify the presence of the Zuppler Online Ordering plugin and verify the version in use. Until an official patch is released, administrators should implement the following mitigations: 1) Restrict administrative access to trusted IP addresses and enforce strong multi-factor authentication to reduce the risk of compromised admin accounts. 2) Educate administrators about phishing risks and the dangers of clicking unsolicited links, especially those that could trigger administrative actions. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious POST requests to the 'zuppler-online-ordering-options' page that lack valid nonces or originate from unusual sources. 4) Monitor web server and application logs for unusual changes to plugin settings or unexpected POST requests. 5) Consider temporarily disabling or removing the plugin if it is not critical to business operations until a patch is available. 6) Follow closely for vendor updates and apply patches immediately upon release. 7) Implement Content Security Policy (CSP) headers to limit the impact of any injected scripts.
