CVE-2026-1792 in Geo Widget Plugin
Summary
by MITRE • 02/14/2026
The Geo Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the URL path in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Geo Widget plugin for WordPress presents a critical security vulnerability classified as CVE-2026-1792, affecting all versions up to and including 1.0. This vulnerability manifests as a stored cross-site scripting flaw that exploits insufficient input sanitization and output escaping mechanisms within the plugin's URL path handling functionality. The flaw allows unauthenticated attackers to inject malicious web scripts into the plugin's data storage, which then executes whenever any user accesses the compromised page. This type of vulnerability falls under CWE-79 - Improper Neutralization of Input During Web Page Generation, specifically targeting the failure to properly sanitize user-supplied data before it is stored and subsequently rendered in web pages. The attack vector is particularly concerning because it does not require authentication, enabling malicious actors to compromise the plugin's functionality without needing valid user credentials.
The technical implementation of this vulnerability stems from the plugin's failure to properly validate and sanitize URL parameters before storing them in the WordPress database. When users access pages that contain the injected script through the URL path, the malicious code executes in the context of the victim's browser session. This stored nature of the vulnerability means that the malicious payload persists in the database and affects all users who view the compromised content, making it a persistent threat. The vulnerability directly impacts the principle of least privilege and proper input validation, as the plugin fails to implement adequate sanitization measures that would prevent malicious data from being stored and subsequently executed. From an operational perspective, this vulnerability creates a significant risk for WordPress sites using the Geo Widget plugin, as attackers can potentially steal session cookies, redirect users to malicious sites, or perform other malicious actions that compromise user security and site integrity.
The operational impact of CVE-2026-1792 extends beyond simple script execution, as it provides attackers with a foothold for more sophisticated attacks within the WordPress environment. This vulnerability aligns with ATT&CK technique T1566.001 - Phishing: Spearphishing Attachment, where the malicious scripts can be used to harvest user credentials or deliver additional malware payloads. The stored nature of the XSS vulnerability means that even users who do not directly interact with the malicious URL path may be affected when the compromised content is displayed in various contexts such as admin panels or user-facing pages. Security practitioners should note that this vulnerability represents a failure in the web application's security architecture, specifically in input validation and output escaping controls that are fundamental to preventing cross-site scripting attacks. The implications for organizations using WordPress sites with this plugin are significant, as the vulnerability can be exploited to perform unauthorized actions on behalf of authenticated users or to establish persistent access to compromised systems.
Mitigation strategies for CVE-2026-1792 should prioritize immediate plugin updates to versions that address the input sanitization and output escaping deficiencies. Organizations should implement comprehensive input validation measures that sanitize all user-supplied data before storage, including URL paths and other parameters. The implementation of Content Security Policy headers can provide additional protection against script execution, though this should not be considered a substitute for proper input sanitization. Security monitoring should include detection of anomalous URL patterns and unexpected script execution within the WordPress environment. Regular security audits of WordPress plugins should be conducted to identify similar vulnerabilities, with particular attention to plugins that handle user input through URL parameters or other dynamic content sources. System administrators should also consider implementing web application firewalls that can detect and block known XSS attack patterns, while maintaining detailed logging of plugin interactions for forensic analysis purposes. The vulnerability demonstrates the critical importance of proper security controls in web applications and serves as a reminder of the need for continuous security testing and validation of all input handling mechanisms within WordPress plugins.
