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'), access fs, and use other Node.js APIs in the host engine process outside the sandbox. An authenticated user who can create a Code step can read environment secrets including APENCRYPTIONKEY and APJWTSECRET, read or write files, and reach internal services. This issue is fixed in version 0.80.0.
