## QNAP NAS: Plex2Shell exploit
Severity: unknown. Patch status: fix status unknown.
Affected: QNAP NAS

Threat actors are exploiting a four-flaw chain to hack the Plex Media Server application on QNAP NAS devices.

## Steps
1. This touches infrastructure (self-hosted). Look in terraform, ansible, cloud-init, Dockerfiles and docs for the product and version we run. If it isn't in the repo, say so and list what a human should check on the box.
2. No source names a fix yet; check the vendor advisory. Until one ships: restrict network access to it.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.

If you have the pwned.coffee MCP server (https://pwned.coffee/mcp), call lookup_cve for the latest, and check_repo with this repo's lockfiles, Dockerfiles and workflows for a full receipt.
