Description

Versions of cordova-plugin-inappbrowser prior to 3.1.0 are vulnerable to Privilege Escalation. A website running in the InAppBrowser webview on Android could execute arbitrary JavaScript in the main application's webview using a specially crafted gap-iab: URI. This affects Cordova Android applications using the package.

Recommendation

Upgrade to version 3.1.0 or later.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cordova-plugin-inappbrowser, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update cordova-plugin-inappbrowser to 3.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c6pw-q7f2-97hv is resolved across your whole dependency graph.

  3. Workarounds

    Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
