## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

When WScreenctl() is invoked (via the bundled g.mjs entry or the documented systemd/Task Scheduler service units), the package starts a Hapi HTTP server bound to 0.0.0.0:7000 with CORS enabled and no authentication. POST /chrome/evaluate passes the request body's \`script\` field directly to Playwright's page.evaluate, allowing arbitrary JavaScript execution inside the controlled Chrome instance. POST /keyboard/type, /keyboard/key, and /mouse/\* forward HTTP-supplied text, key names, and coordinates into xdotool or w-mousekey/AHK, driving system-wide keyboard and mouse input on the host desktop. Because the listener binds to all interfaces with no credential check, any party reachable on the network — LAN, adjacent VLAN, or an internet-routable interface — can execute JavaScript in the browser session and drive arbitrary keystrokes and clicks on the operator's machine, which can be used to open a terminal, type shell commands, and achieve full host RCE. The dist bundle also contains child\_process usage tied to ping and POST primitives consistent with this HTTP dispatch surface.
