Execution with Unnecessary Privileges in arc-electron
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
@advanced-rest-client/basenpmDescription
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 dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @advanced-rest-client/base. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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.
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.
How O3 protects you
O3 pinpoints whether GHSA-v3wr-67px-44xg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-v3wr-67px-44xg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-v3wr-67px-44xg in your dependencies?
O3 detects GHSA-v3wr-67px-44xg across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
