The vulnerability identified as CVE-2025-2169 affects the WPCS – WordPress Currency Switcher Professional plugin, a popular tool used to manage currency switching on WordPress e-commerce sites. The flaw is a code injection vulnerability categorized under CWE-94, stemming from improper control over the generation and execution of code. Specifically, the plugin fails to properly validate user-supplied input before passing it to WordPress's do_shortcode function, which processes shortcodes embedded in content. This improper validation allows unauthenticated attackers to craft malicious requests that execute arbitrary shortcodes on the target site. Since shortcodes can invoke PHP functions or other plugin features, this can lead to unauthorized code execution, potentially compromising site confidentiality, integrity, and availability. The vulnerability affects all versions up to and including 1.2.0.4. The CVSS v3.1 base score is 7.3, reflecting a high severity due to network attack vector, no required privileges or user interaction, and impacts on confidentiality, integrity, and availability. No patches or fixes have been published at the time of disclosure, and no known exploits have been observed in the wild. The vulnerability is critical for sites that rely on this plugin, especially those handling sensitive financial transactions or customer data.

The impact of CVE-2025-2169 is significant for organizations using the vulnerable plugin. Successful exploitation can allow attackers to execute arbitrary shortcodes remotely without authentication, potentially leading to unauthorized code execution. This can result in data leakage (confidentiality impact), unauthorized modification of site content or configuration (integrity impact), and disruption or defacement of the website (availability impact). For e-commerce sites, this could mean theft of customer data, manipulation of pricing or currency information, or complete site takeover. The ease of exploitation and lack of required privileges increase the risk of widespread attacks. Organizations may face reputational damage, regulatory penalties for data breaches, and operational downtime. The vulnerability also opens a pathway for further attacks such as malware deployment, phishing, or lateral movement within the hosting environment.

Immediate mitigation involves disabling the WPCS – WordPress Currency Switcher Professional plugin until a security patch is released. Administrators should monitor the vendor’s official channels for updates and apply patches promptly once available. In the interim, implementing web application firewall (WAF) rules to detect and block suspicious shortcode execution patterns can reduce risk. Restricting access to the WordPress admin and plugin endpoints via IP whitelisting or VPN can limit exposure. Regularly auditing installed plugins and removing unused or unmaintained ones reduces attack surface. Additionally, enforcing the principle of least privilege for WordPress users and maintaining up-to-date backups ensures recovery capability. Security teams should also monitor logs for unusual shortcode execution attempts and consider deploying intrusion detection systems tailored to WordPress environments.
