Description

Impact

When the end-user click on the response header that contains a link the target will be opened in ARC new window. This window will have the default preload script loaded which allows the scripts embedded in the link target to execute any logic that ARC has access to from the renderer process, which includes file system access, data store access (which may contain sensitive information), and some additional processes that only ARC should have access to.

Patches

This is patched in version 17.0.9.

Workarounds

Do not click onto any link in the response headers view.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @advanced-rest-client/base, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update @advanced-rest-client/base to 0.1.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v3wr-67px-44xg is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
