From 82f376a0647ddaff9442cf5fc845b1cfb38a4aab Mon Sep 17 00:00:00 2001 From: gonzaloriestra <14979109+gonzaloriestra@users.noreply.github.com> Date: Wed, 20 May 2026 01:19:19 +0000 Subject: [PATCH 1/2] [Security] Harden openURL protocol validation Restrict allowed protocols in `openURL` to `http:`, `https:`, and `file:`. This prevents the execution of dangerous protocols like `javascript:` or `data:` via the system's default opener. - Added protocol validation using `URL` constructor in `packages/cli-kit/src/public/node/system.ts`. - Added comprehensive regression tests in `packages/cli-kit/src/public/node/system.test.ts`. - Updated `.jules/sentinel.md` with critical learnings. --- .jules/sentinel.md | 4 + .../cli-kit/src/public/node/system.test.ts | 76 +++++++++++++++++++ packages/cli-kit/src/public/node/system.ts | 10 +++ 3 files changed, 90 insertions(+) create mode 100644 .jules/sentinel.md diff --git a/.jules/sentinel.md b/.jules/sentinel.md new file mode 100644 index 0000000000..4a82dd5440 --- /dev/null +++ b/.jules/sentinel.md @@ -0,0 +1,4 @@ +## 2026-05-20 - Protocol validation in system openers +**Vulnerability:** The `openURL` function allowed any URL protocol to be passed to the system's default opener (via the `open` library).

This prevents the execution of dangerous protocols like `javascript:` or `data:` via the system's default opener.
