Insufficient validation of untrusted input in WebView in Google Chrome on Android prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-17736 involves insufficient validation of untrusted input within the WebView component of Google Chrome on Android. Specifically, in versions before 151.0.7922.72, a remote attacker with control over the renderer process might exploit this flaw to perform a sandbox escape via a specially crafted HTML page. This could undermine the security boundaries intended to isolate web content from the underlying system.
Potential Impact
If successfully exploited, this vulnerability could allow an attacker who has compromised the renderer process to break out of the sandbox environment, potentially gaining elevated privileges or access beyond the intended restrictions of the WebView sandbox. This increases the risk of further system compromise on affected devices.
Mitigation Recommendations
A fix is available in Google Chrome on Android version 151.0.7922.72 and later. Users and administrators should update to this version or a later one to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
