At a glance
CVE-2024-10621 is a medium-severity Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability in the Simple Shortcode for Google Maps WordPress plugin, affecting versions <= 1.5.4. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.6; sites on affected versions should update now. Disclosed November 2024, reported by Akbar Kustirama.
Vulnerability Overview
The Simple Shortcode for Google Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's pw_map shortcode in all versions up to, and including, 1.5.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as <, >, and & that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.
Remediation
Update to version 1.6, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Simple Shortcode for Google Maps 1.6 closes this, and updating the plugin is the step that ends it.
