From 7f24707eadfdd6931fe62f4ccbad46c694a1e6dd Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 23 Oct 2026 14:57:43 +0000 Subject: [PATCH] fix(functions-compiler): report Node v22.23.4 as process.version in the shim workerd's nodejs_compat pins process.version to v22.19.0. stripe-node sends it as lang_version in X-Stripe-Client-User-Agent, and Stripe now warns customers that their Node is affected by CVE-2026-111497, patched in 22.23.4. Set it before user code loads.
