Overview

The GEO my WordPress plugin for WordPress (versions up to 4.0) contains a Stored Cross-Site Scripting vulnerability (CVE-2023-5467) discovered in October 2023. The vulnerability stems from insufficient input sanitization and output escaping on user-supplied attributes in shortcodes (NIST NVD, WPScan).

Technical details

The vulnerability is classified as a Cross-Site Scripting (XSS) issue with a CVSS v3.1 base score of 5.4 (Medium) according to NVD, and 6.4 (Medium) according to Wordfence. The vulnerability exists due to the plugin's failure to validate and escape certain shortcode attributes before outputting them back in a page or post where the shortcode is embedded (NIST NVD).

Impact

This vulnerability allows authenticated attackers with contributor-level permissions or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses the compromised page (NIST NVD).

Mitigation and workarounds
