Executive Summary

CVE-2026-76178 is a stored Cross-Site Scripting (XSS) vulnerability in OCS Inventory NG's Ocsreports. It affects the notification template functionality via the /ocsreports/?function=notification endpoint. An administrator can inject malicious HTML or JavaScript into templates, which is stored without sanitization and later executed when other administrators view the templates.

Detection Guidance

Check OCS Inventory NG version for updates. Inspect notification templates in /ocsreports/?function=notification for suspicious HTML/JS content. Monitor admin sessions for unexpected behavior or unauthorized actions.

Impact Analysis

This vulnerability allows an attacker with admin access to execute arbitrary JavaScript in the context of other administrators' sessions. This could lead to session hijacking, unauthorized actions, or further compromise of the application or network.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating confidentiality requirements in GDPR and HIPAA. It may result in non-compliance due to insufficient protection against session hijacking and data exposure.

Mitigation Strategies

Upgrade to OCS Inventory NG version 2.12.6 or later. Review and sanitize existing notification templates. Restrict admin access to template customization until patched. Monitor for unusual admin activity.
