Google Chrome: Improper input validation in Omnibox on Android
Summary
Improper input validation in the Omnibox (address and search bar) of Google Chrome for Android before 156.0.8078.47 allows a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attack requires the victim to open a crafted HTML page; no login is needed. The CVSS 3.1 base score is 8.8, while Chromium rates the severity as Low.
Affected
- Google Chrome for Android before 156.0.8078.47
- The CNA JSON record lists 156.0.8078.47 as affected, which contradicts the description; the description is treated as correct.
Fixed in
- Google Chrome for Android 156.0.8078.47 or later
- Later Android builds have been reported (e.g. 156.0.8078.79 via Google Play, and 157.0.8103.14 on 22 October 2026 according to Wikipedia); verify the current build in the Play Store.
Workaround
- Not needed where a fixed build is installed.
- No vendor-documented workaround found. Unknown for unpatched devices.
Exploitation
- Not listed in CISA KEV according to one tracker; verify directly in the CISA KEV catalogue.
- Public proof of concept: none found. Unknown.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- EPSS 0.00406 (very low).
Our recommendation
- Check the Chrome version on all Android phones and tablets and require at least the current Play Store build.
- Make sure Google Play auto-update is enabled, or enforce updates via MDM.
- Verify against the Google advisory before closing this CVE, and check whether CVE-2026-113099 (similar description) is relevant too.
