Cloudflare Workers Spectre Attack Leaks JWT From Co-Located Worker at 12 Bits/Second

Cybersecurity researchers have disclosed details of a remote Spectre attack against Cloudflare Workers that leaked a JSON Web Token JWT from a co-located Worker in the production environment at up to 12 bits per second, 360 times the rate of an earlier attack demonstrated in 2021. The end-to-end...

CVE-2026-73083 Activepieces: V8 Isolate Sandbox Bypass via importFresh Module Loading

Activepieces is an open source AI workflow automation platform. Prior to 0.80.0, in SANDBOXCODEONLY mode, the engine loads the compiled user module with importFresh, a wrapper around Node.js require, before the V8 isolate is applied. Top-level module code can therefore call require'childprocess',...

CVE-2026-73083

Activepieces prior to 0.80.0 runs user code in SANDBOX_CODE_ONLY by loading modules with importFresh() before the V8 isolate is applied. This allows top-level code to call Node.js APIs (e.g., child_process, fs) in the host engine process, enabling an authenticated Code step user to read environme...

CVE-2022-39266: Protection Mechanism Failure

isolated-vm is a library for nodejs which gives the user access to v8's Isolate interface. In versions 4.3.6 and prior, if the untrusted v8 cached data is passed to the API through CachedDataOptions, attackers can bypass the sandbox and run arbitrary code in the nodejs process. Version 4.3.7...
