Summary
UltrafastSecp256k1 is a high-performance, multi-backend secp256k1 engine with reproducible audit evidence, compatibility shims, and profile-based review scopes. Prior to version 4.2.0, UltrafastSecp256k1's ECDSA adaptor pre-signature verification accepts forged adaptor pre-signatures whose "r" value is not cryptographically bound to the adaptor point "T". This issue has been patched in version 4.2.0.
Risk Assessment
An attacker could forge ECDSA adaptor pre-signatures, potentially bypassing cryptographic mechanisms and leading to transaction or signature forgery. This may undermine trust in systems relying on this engine.
Recommendation
Upgrade UltrafastSecp256k1 to version 4.2.0 or later. Verify signature integrity in systems using this engine.

- 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.
