CVE-2026-1792 identifies a stored Cross-Site Scripting (XSS) vulnerability in the Geo Widget plugin for WordPress developed by owencutajar. This vulnerability affects all versions up to and including 1.0. The root cause is insufficient input sanitization and output escaping of the URL path parameter, which allows an unauthenticated attacker to inject arbitrary JavaScript code into pages generated by the plugin. When a user accesses a page containing the injected script, the malicious code executes in the context of the victim's browser. This can lead to theft of session cookies, user credentials, or execution of unauthorized actions on behalf of the user. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The CVSS v3.1 base score is 6.1, indicating medium severity, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. This means the attack can be launched remotely without privileges, requires low attack complexity, no authentication, but does require user interaction to trigger. The scope is changed (S:C), indicating the vulnerability affects resources beyond the vulnerable component. Confidentiality and integrity impacts are low, while availability is unaffected. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly to prevent exploitation. The plugin is commonly used in WordPress sites to display geographic information, making it a potentially attractive target for attackers aiming to compromise site visitors or administrators.

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of user data on websites using the Geo Widget plugin. Attackers can exploit the stored XSS to hijack user sessions, steal sensitive information such as login credentials, or perform actions on behalf of users, potentially leading to account compromise or unauthorized transactions. Public-facing websites, especially those handling personal data or financial transactions, are at higher risk. The vulnerability could also be leveraged as a stepping stone for more complex attacks, including phishing or malware distribution. Given the widespread use of WordPress across Europe, organizations in sectors such as e-commerce, government, education, and media could be impacted. The medium severity score reflects a moderate but non-negligible threat level, emphasizing the need for timely remediation to avoid reputational damage, regulatory penalties under GDPR for data breaches, and operational disruptions.

1. Monitor for official patches or updates from the plugin developer and apply them immediately once available. 2. If no patch is currently available, consider temporarily disabling the Geo Widget plugin or replacing it with a secure alternative. 3. Implement a Web Application Firewall (WAF) with rules specifically designed to detect and block XSS payloads targeting URL paths and query parameters. 4. Enforce strict Content Security Policies (CSP) to restrict the execution of inline scripts and limit the sources of executable code on affected websites. 5. Conduct regular security audits and code reviews of custom plugins or themes that interact with the Geo Widget to ensure no additional injection points exist. 6. Educate website administrators and developers about secure coding practices, particularly input validation and output encoding. 7. Monitor website logs and user reports for signs of suspicious activity or exploitation attempts. 8. Employ security headers such as X-XSS-Protection and HTTPOnly cookies to reduce the impact of potential XSS attacks. 9. Encourage users to keep browsers updated and use security extensions that can help detect malicious scripts.
