Atomic Edge analysis of CVE-2026-7462 (metadata-based):
This reflected cross-site scripting vulnerability in the VatanSMS WP SMS plugin (slug: wp-sms-vatansms-com) allows unauthenticated attackers to inject arbitrary JavaScript into admin pages via the ‘page’ parameter. The vulnerability affects all versions up to and including 1.01, and no patched version is available from WordPress.org. The CVSS score of 6.1 (Medium) reflects the need for user interaction (an admin clicking a crafted link) and the limited impact to confidentiality and integrity.
Root Cause:
The CWE-79 classification and the description point to insufficient input sanitization and output escaping on the ‘page’ parameter. In WordPress plugins, parameters like ‘page’ are often used in admin menu slugs and echoed directly into page output without proper escaping. Atomic Edge analysis infers that the vulnerable code likely calls echo or print on $_GET[‘page’] or $_REQUEST[‘page’] without passing it through esc_html(), esc_attr(), or wp_kses(). The plugin’s admin page loader probably constructs a menu slug or sends the page value directly to the browser. Because no source code diff is available, this root cause is inferred from the CWE and description, not confirmed from code.
Exploitation:
An attacker crafts a malicious URL that points to the WordPress admin area, likely /wp-admin/admin.php?page=alert(document.cookie). The attacker then tricks an authenticated administrator with sufficient privileges into clicking this link. Because the plugin fails to sanitize the ‘page’ parameter, the injected script executes in the admin context. The attacker does not need authentication; they only need to deceive a logged-in admin. The attack vector is network-based, low complexity, and requires no privileges.
Remediation:
The plugin authors must properly sanitize and escape the ‘page’ parameter. The recommended fix is to use sanitize_text_field() or similar for input sanitization, and then esc_html() or esc_attr() when outputting the value in HTML context. Since no patched version is available, site administrators should disable the plugin or apply a virtual patch via a web application firewall. Atomic Edge recommends using the ModSecurity rule provided below as a temporary mitigation.
Impact:
Successful exploitation allows an attacker to execute arbitrary JavaScript in the browser of an authenticated WordPress administrator. This can lead to session hijacking, forced administrative actions (e.g., creating new admin users, modifying plugins), data exfiltration from the admin dashboard, or defacement of the WordPress site. Because the admin has elevated privileges, the attacker can effectively take full control of the WordPress installation.
