CVE-2026-11207 is a critical vulnerability in Google Chrome's Autofill feature prior to version 149.0.7827.53. It involves insufficient validation of untrusted input, which could allow a remote attacker to potentially escape the browser sandbox via malicious network traffic. The vulnerability has a high CVSS score of 9.6, indicating severe impact on confidentiality, integrity, and availability.
AI Analysis
Technical Summary
This vulnerability arises from improper validation of untrusted input within the Autofill component of Google Chrome versions before 149.0.7827.53. Exploiting this flaw could enable a remote attacker to perform a sandbox escape, thereby potentially gaining elevated privileges or executing arbitrary code outside the browser's restricted environment. The CVSS vector indicates the attack requires no privileges but does require user interaction, and the impact is critical across confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could lead to a sandbox escape, allowing an attacker to bypass Chrome's security boundaries. This can result in full compromise of the affected system's confidentiality, integrity, and availability. No known exploits are currently reported in the wild.
Mitigation Recommendations
A fix is available in Google Chrome version 149.0.7827.53. Users and administrators should update to this version or later to remediate the vulnerability. The vendor advisory linked provides official update information. No additional mitigations are specified.
