Summary
An authenticated command injection vulnerability in TP-Link Archer BE800 V1 allows an attacker with administrative access to execute arbitrary system commands with root privileges by injecting shell metacharacters via a VPN connection. Successful exploitation may enable persistent backdoors, credential theft, LAN reconnaissance, and router-assisted attacks against connected devices.
Risk Assessment
The risk for the organization includes full compromise of the router, which can lead to persistent attacker presence in the network, credential theft, and attacks on other devices in the LAN.
Recommendation
It is recommended to immediately update the firmware of the TP-Link Archer BE800 router to the latest version with fixes. Also restrict administrative access to trusted users and use strong passwords.

- CVE-2026-120338Critical
The Generative UI sandbox in prefab-ui runs caller-supplied Python inside Pyodide (WebAssembly) in a Deno subprocess, but from 0.14.0 through 0.20.2 Deno starts with unrestricted --allow-read, --allow-write, and --allow-net, and the Deno API remains on the JavaScript global object. This lets Python call Deno.readTextFileSync and Deno.writeTextFileSync, enabling file read/write as the server OS user and persistent code execution via a .pth file in site-packages.

- CVE-2026-120308Critical
In Beta9, a tenant can attach a volume when deploying a function, endpoint, or task queue. The gateway builds the host path by joining the shared volumes root, the workspace name, and the volume identifier from the stub configuration, without checking that the identifier names a volume owned by that workspace. Parent-directory segments in the identifier collapse the joined path to the worker's filesystem root, which is bind-mounted read-write into the sandbox, allowing read and write access to the worker's files, including other tenants' volumes.
- CVE-2026-120307Critical
The Beta9 worker serves the sandbox file API from outside the container. getHostPathFromContainerPath turns the tenant's container path into a worker path; if the unresolved path starts with a mount destination (including the default /tmp/.beta9), the remainder is joined onto that mount's source with filepath.Join, which cleans parent-directory segments after the prefix check. A long enough run of such segments names any absolute path on the worker, and a path matching no mount is opened in the worker's filesystem, following absolute symbolic links. A tenant with a workspace token and a running sandbox can read, write, list, and delete files on the worker as root, including other tenants' files.
