Google Chrome for iOS: Improper input validation allows code execution
Summary
Improper input validation in the Mobile component of Google Chrome for iOS (before 155.0.8059.39) can be abused by a remote attacker. A user must first be tricked by social engineering into opening a crafted HTML page. If successful, the attacker could potentially execute arbitrary code outside the Chrome sandbox. NVD rates the issue 9.6 (critical), while Google rates it Medium.
Affected
- Google Chrome for iOS prior to 155.0.8059.39 (per CVE description)
- Version details for iOS conflict across sources; the App Store build should be checked directly
Fixed in
- Fixed in Chrome 155.0.8059.39 according to the CVE record; the iOS build carrying the fix is not confirmed by the vendor
- Do not treat 155.0.8059.37 as fixed until confirmed
- Install the newest Chrome version from the App Store
Workaround
- No workaround documented. Apply the update.
- Avoid opening untrusted links and be cautious with pages requesting unexpected actions.
Exploitation
- CISA SSVC: Exploitation none, not automatable, total technical impact.
- No public proof of concept found.
- No known exploitation in the wild in the sources reviewed. Check the CISA KEV catalog to confirm.
Our recommendation
- Inventory Chrome on iOS and iPadOS devices, including BYOD devices, and record versions.
- Update Chrome through the App Store to the newest build, not only 155.0.8059.39.
- Enforce updates through MDM for managed devices.
- Train staff to recognise phishing and malicious links.
- Monitor the CISA KEV catalog and Google advisories for changes.
