CVE-2026-13037: 
Google Chrome vulnerability analysis and mitigation

CVE-2026-13037 is a use-after-free vulnerability in the WebView component of Google Chrome on Android, allowing a local attacker to execute arbitrary code inside a sandbox via a crafted HTML page. It affects all Google Chrome versions prior to 149.0.7827.197 on Android. The vulnerability was reported by Google on June 14, 2026, and publicly disclosed on June 24, 2026, alongside a stable channel update. It carries a CVSS v3.1 base score of 7.8 (High) (Chrome Releases, GitHub Advisory).

The vulnerability is classified as CWE-416 (Use After Free), occurring in the WebView component of Chrome on Android. A use-after-free condition arises when memory that has been freed is subsequently referenced or reused, potentially allowing an attacker to control program execution by manipulating the freed memory region. Exploitation requires a local attacker to trick a user into viewing a specially crafted HTML page within Chrome's WebView, which triggers the memory corruption and enables arbitrary code execution within the sandbox. The Chromium issue tracker references bug ID 523721871 for this vulnerability (Chrome Releases, GitHub Advisory).

Successful exploitation allows an unauthenticated local attacker to execute arbitrary code within the Chrome WebView sandbox on Android devices, with high impact to confidentiality, integrity, and availability. While execution is constrained to the sandbox environment, this could serve as a stepping stone for sandbox escape chains or enable data theft from within the WebView context. User interaction is required, as the victim must open a crafted HTML page (GitHub Advisory, Chrome Releases).

Google has released a patch in Chrome version 149.0.7827.197 for Android, which addresses this vulnerability. Users should update Chrome on Android to version 149.0.7827.197 or later immediately, preferably by enabling automatic updates. As an additional precaution, users should avoid opening untrusted HTML content in Chrome WebView until the update is applied (Chrome Releases, GitHub Advisory).

The Chrome 149 security update received coverage from several cybersecurity news outlets, including CyberSecurityNews and CyberPress, which highlighted the batch of 18 security fixes — including four rated Critical — addressed in this release. Beyond Machines noted that Google patched 18 flaws in the Chrome 149 update.
