CVE-2026-15469
HighCVSS 7.7Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
The use of hard-coded cryptographic key vulnerability has been identified in the mesh functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6. A shared RSA-512 mesh group private key is present in the affected firmware and is used by the mesh protocol for node authentication. An attacker who obtains the firmware image and has local network access may be able to authenticate as a mesh node without possessing a device-specific credential. Successful exploitation may allow an unauthenticated adjacent attacker to impersonate a trusted mesh node and bypass mesh node authentication, which may permit unauthorized changes to device or mesh configuration, affecting confidentiality, integrity and availability.
Risk Assessment
An attacker within network range may gain control over the device or mesh network, potentially leading to confidentiality, integrity, and availability breaches.
Recommendation
Update the device firmware to the latest version that addresses this vulnerability, if a patch is available.

- 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.
