CVE-2025-47673 is a high-severity reflected Cross-site Scripting (XSS) vulnerability affecting the Arconix Shortcodes plugin developed by tychesoftwares, specifically versions up to 2.1.16. The vulnerability arises due to improper neutralization of user-supplied input during web page generation, classified under CWE-79. This flaw allows an attacker to inject malicious scripts into web pages that are dynamically generated by the plugin, which are then reflected back to users without proper sanitization or encoding. Exploitation requires no privileges (PR:N) but does require user interaction (UI:R), such as clicking a crafted link or visiting a maliciously crafted URL. The vulnerability has a CVSS 3.1 base score of 7.1, indicating high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), and a scope change (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes limited confidentiality, integrity, and availability losses (C:L/I:L/A:L), as attackers can execute arbitrary scripts in the context of the victim's browser, potentially stealing session tokens, performing actions on behalf of the user, or defacing content. No known exploits are currently reported in the wild, and no patches have been linked yet. The plugin is commonly used in WordPress environments to add shortcode functionality, which is popular among websites for enhancing content presentation and functionality. The reflected XSS nature means the malicious payload is not stored but delivered via crafted requests, making it suitable for targeted phishing or social engineering attacks.

For European organizations, this vulnerability poses significant risks, especially for those relying on WordPress websites that utilize the Arconix Shortcodes plugin. Exploitation could lead to session hijacking, unauthorized actions performed with user privileges, and potential data leakage. This is particularly critical for organizations handling sensitive customer data, financial transactions, or internal communications via web portals. The reflected XSS can be leveraged to bypass same-origin policies, enabling attackers to steal cookies or tokens, leading to account compromise. Additionally, reputational damage and regulatory consequences under GDPR could arise if personal data is exposed or manipulated. The vulnerability's network attack vector and low complexity make it accessible to a wide range of attackers, increasing the likelihood of targeted attacks against European entities with public-facing WordPress sites. The scope change indicates that the impact could extend beyond the plugin itself, potentially affecting other components or user sessions.

European organizations should immediately audit their WordPress installations to identify the presence and version of the Arconix Shortcodes plugin. Until an official patch is released, organizations should consider temporarily disabling or removing the plugin to eliminate exposure. Web application firewalls (WAFs) should be configured with rules to detect and block reflected XSS payloads targeting the plugin's endpoints. Input validation and output encoding should be enforced at the application level where feasible. Security teams should monitor web traffic for suspicious patterns indicative of XSS exploitation attempts. User awareness training should emphasize caution when clicking on unsolicited links, especially those that could trigger reflected XSS attacks. Once a patch is available, prompt application of updates is critical. Additionally, implementing Content Security Policy (CSP) headers can help mitigate the impact by restricting the execution of unauthorized scripts. Regular security assessments and penetration testing focusing on web application vulnerabilities should be conducted to detect similar issues proactively.
