Insufficient validation of untrusted input in Chrome for iOS in Google Chrome on iOS prior to 151.0.7922.72 allowed a remote attacker to bypass navigation restrictions via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Navigation restriction bypass in Google Chrome for iOS (versions prior to 151.0.7922.72) enables unauthenticated remote attackers to circumvent browser navigation controls by inducing a user to load a crafted HTML page. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N) confirms network-accessible, low-complexity exploitation with no privilege requirements but mandatory user interaction, yielding high integrity impact with no confidentiality or availability consequences. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the target to be running Google Chrome on Apple iOS with a version strictly below 151.0.7922.72 - this vulnerability does not apply to Chrome on Android, Windows, macOS, or Linux. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 6.5 Medium score reflects a network-accessible, zero-prerequisite attack limited by required user interaction (UI:R) and a scope-unchanged impact boundary. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker crafts a malicious HTML page that exploits the input validation flaw in Chrome for iOS's navigation subsystem and hosts it on an attacker-controlled domain. The victim, running an unpatched version of Chrome on an iOS device, is directed to the page via a phishing link, malicious advertisement, or redirect chain. …
Remediation	Upgrade Google Chrome on iOS to version 151.0.7922.72 or later, which constitutes the vendor-released patch for this vulnerability per the stable channel advisory at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report.
