Security readout for executives and security teams
Plain-English summary
This flaw affected Google Chrome on Android before 106.0.5249.62. If a user installed a malicious application, that app could abuse Chrome Custom Tabs to bypass same-origin policy, potentially changing web content or actions that should have been isolated.
Executive priority
Treat as a moderate mobile-browser risk. Prioritize patch compliance for managed Android fleets and app-install controls, but this is not supported as actively exploited by the provided evidence.
Technical view
CVE-2022-3310 is insufficient policy enforcement in Chrome Custom Tabs on Android. The CVSS vector indicates network attack surface, low complexity, no privileges, required user interaction, unchanged scope, no confidentiality impact, high integrity impact, and no availability impact.
Likely exposure
Exposure is limited to Android devices running Chrome before 106.0.5249.62, especially environments where users can install unmanaged apps. The sources do not identify affected non-Chrome products or specific vulnerable app integrations.
Exploitation context
The provided sources require the attacker to convince the user to install an application. CISA KEV is false in the bundle, and no cited source confirms active exploitation.
Researcher notes
The public description is sparse and references Chromium bug 1240065. Avoid assuming exploit mechanics beyond a crafted Android application abusing Custom Tabs policy enforcement to bypass same-origin policy.
Mitigation direction
- Update Chrome on Android to 106.0.5249.62 or later.
- Use MDM or Play policy to enforce Chrome updates.
- Restrict installation of untrusted Android applications where possible.
- Check Google Chrome release guidance for any newer vendor direction.
Validation and detection
- Inventory Android devices and installed Chrome versions.
- Flag Chrome on Android versions earlier than 106.0.5249.62.
- Confirm managed devices receive Chrome updates automatically.
- Review mobile controls for sideloading or unmanaged app installation.
- Document remaining unmanaged Android device exposure.
