DescriptionCVE.org

Inappropriate implementation in Chrome for iOS in Google Chrome on iOS prior to 149.0.7827.53 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Sandbox escape in Google Chrome for iOS prior to 149.0.7827.53 allows a remote attacker who lures a victim to a malicious page to potentially break out of Chrome's renderer sandbox via crafted HTML. The flaw is rated CVSS 8.8 (High) due to high confidentiality, integrity, and availability impact, though Chromium internally classifies severity as Medium and EPSS exploitation probability is currently very low (0.05%). No public exploit identified at time of analysis.

Technical ContextAI

The vulnerability resides in Chrome for iOS, which under Apple's App Store policy is built on WebKit (not Blink/V8) but layers Chromium's process model and UI on top. CWE-20 (Improper Input Validation) indicates that some input - likely a crafted HTML construct, URL handler, or IPC message between renderer and browser process - is not properly validated before being acted upon, enabling a renderer-context attacker to cross sandbox boundaries. On iOS this typically means escaping the WebContent process's sandboxed entitlements to access broader Chrome browser process privileges, though full system compromise is constrained by Apple's underlying iOS sandbox.

RemediationAI

Vendor-released patch: Google Chrome for iOS 149.0.7827.53. Update Chrome on all iOS devices through the App Store to version 149.0.7827.53 or later, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. No workarounds are documented; until updated, users can reduce exposure by avoiding untrusted links in Chrome on iOS or temporarily switching to Safari (which uses the same underlying WebKit engine but a different browser-process surface), accepting the trade-off of losing Chrome sync and features. Enterprise fleets managing iOS devices via MDM should push the Chrome app update and verify version compliance.
