Full Report
Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Analysis Summary
# Vulnerability: Multiple Vulnerabilities in Google Chrome (June 2026)
## CVE Details
- **CVE ID:** CVE-2026-13281, CVE-2026-13282, CVE-2026-13283
- **CVSS Score:** Not explicitly provided in the advisory, but rated as **Medium-High risk** (Arbitrary Code Execution context).
- **CWE:**
- CVE-2026-13281: Integer Overflow
- CVE-2026-13282: Use After Free
- CVE-2026-13283: Use After Free
## Affected Systems
- **Products:** Google Chrome Browser
- **Versions:**
- Windows and macOS: Versions prior to 149.0.7827.200/201
- Linux: Versions prior to 149.0.7827.200
- **Configurations:** Systems where users operate with high administrative privileges are at increased risk.
## Vulnerability Description
Multiple flaws exist in different components of the Google Chrome browser:
1. **Integer Overflow in Mojo:** A flaw in the Mojo communication framework could be exploited to cause memory corruption.
2. **Use After Free in Payments:** A memory corruption flaw in the Payments component.
3. **Use After Free in AdFilter:** A memory corruption flaw in the AdFilter component.
If successfully exploited, these vulnerabilities allow for **Arbitrary Code Execution (ACE)**. An attacker could execute code within the security context of the current user.
## Exploitation
- **Status:** Not currently reported as exploited in the wild.
- **Complexity:** Medium (typical for memory corruption bugs in modern browsers).
- **Attack Vector:** Network (Drive-By Compromise).
## Impact
- **Confidentiality:** High (Ability to view data)
- **Integrity:** High (Ability to change/delete data or create new accounts)
- **Availability:** High (Ability to install/delete programs and modify system stability)
## Remediation
### Patches
Update Google Chrome to the following versions:
- **Windows/macOS:** 149.0.7827.200/201 or later.
- **Linux:** 149.0.7827.200 or later.
### Workarounds
- **Principle of Least Privilege:** Run the browser as a non-privileged user to limit the scope of a potential compromise.
- **Application Isolation:** Utilize sandboxing or virtualized environments for web browsing.
- **Social Engineering Training:** Educate users to recognize phishing and malicious links that lead to drive-by downloads.
## Detection
- **Indicators of Compromise:** Unexpected browser crashes, unusual outbound network traffic, or unauthorized creation of new user accounts.
- **Detection Methods:** Vulnerability scanners and automated patch management tools to identify outdated browser versions (Safeguard 7.4). Monitoring for unauthorized application installations.
