Stored XSS in LatePoint WordPress Plugin

Publication date: 2026-08-06

Last updated on: 2026-08-06

Assigner: Wordfence

Description
The LatePoint plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'btn_wrapper_classes' attribute of the 'latepoint_resources' shortcode in all versions up to, and including, 5.3.2. This is due to insufficient input sanitization and output escaping in the 'locations' branch of the 'shortcode_latepoint_resources' function. 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.

Executive Summary

This is a Stored Cross-Site Scripting (XSS) vulnerability in the LatePoint WordPress plugin. It allows authenticated attackers with contributor-level access or higher to inject malicious scripts via the 'btn_wrapper_classes' attribute in the 'latepoint_resources' shortcode. The flaw exists due to insufficient input sanitization and output escaping in the 'locations' branch of the 'shortcode_latepoint_resources' function.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the LatePoint plugin for versions up to 5.3.2. Check for malicious scripts in pages using the 'latepoint_resources' shortcode with the 'btn_wrapper_classes' attribute. Review contributor-level user activity logs for unauthorized edits.

Impact Analysis

An attacker could inject malicious scripts into your WordPress site. When users access the infected page, the script executes in their browser, potentially stealing session cookies, redirecting to phishing sites, or performing actions on behalf of the user. This requires only contributor-level access, making it easier for attackers to exploit.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, violating GDPR's data protection principles and HIPAA's security requirements. If exploited, it may result in data breaches, leading to legal penalties, reputational damage, and loss of trust. Organizations must address it to maintain compliance.

Mitigation Strategies

Immediately update the LatePoint plugin to the latest version beyond 5.3.2. Remove or restrict contributor-level access to untrusted users. Scan WordPress sites for injected scripts and clean affected pages. Monitor for unusual activity.
