DescriptionCVE.org

Inappropriate implementation in Chrome for iOS in Google Chrome on iOS prior to 151.0.7922.72 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Sandbox escape in Google Chrome for iOS before version 151.0.7922.72 allows a remote attacker to break out of the browser's security boundary when a victim opens a crafted HTML page. Rated High by Chromium and carrying a 9.6 CVSS due to a scope-changing, high-impact outcome requiring only user interaction, though there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.29%, 21st percentile). A vendor-released patch is available and CISA SSVC currently records exploitation status as none.

Technical ContextAI

The flaw is classified under CWE-693 (Protection Mechanism Failure), describing a case where an existing security control - here the browser sandbox that isolates untrusted web content from the host device and other origins - is implemented inappropriately and can be bypassed rather than a memory-corruption primitive per se. The affected component is the Chrome for iOS application (CPE cpe:2.3:a:google:chrome), which on iOS is constrained by Apple's mandatory WebKit engine, so the 'sandbox escape' concerns Chrome's own process/isolation model layered atop iOS. A crafted HTML page triggers the weak protection boundary, and the CVSS scope-change flag (S:C) reflects that the impact crosses from the sandboxed renderer context into a more privileged security domain.

RemediationAI

Vendor-released patch: update Chrome for iOS to 151.0.7922.72 or later, which is the primary and recommended fix; on iOS this is delivered through the Apple App Store, so ensure automatic app updates are enabled or push the update via MDM for managed fleets. Refer to Google's advisory at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html and the Chromium issue at https://issues.chromium.org/issues/513142464. Until devices are updated, reduce exposure by advising users not to open untrusted links or attacker-supplied HTML pages and by restricting browsing to trusted sites, since exploitation depends on loading a crafted page (UI:R); organizations can layer web/URL filtering or a secure web gateway to block known-malicious pages, accepting the trade-off that such controls cannot catch all novel malicious HTML and may impact browsing convenience.
