CVE-2026-17856: Inappropriate implementation in Google Chrome
CVE-2026-17856 is a medium severity vulnerability in Google Chrome on Mac platforms prior to version 151.0.7922.72. It involves an inappropriate implementation in the Network component that could allow a remote attacker, who has already compromised the renderer process, to potentially escape the sandbox by using a crafted HTML page. This vulnerability affects the security boundary of the browser sandbox, which is designed to isolate processes and limit the impact of compromises. No known exploits are reported in the wild at this time.
AI Analysis
Technical Summary
This vulnerability in Google Chrome for Mac arises from an inappropriate implementation in the Network component that enables a remote attacker with control over the renderer process to potentially perform a sandbox escape via a crafted HTML page. The sandbox escape could allow the attacker to break out of the restricted environment of the renderer process, potentially leading to greater system compromise. The issue affects versions prior to 151.0.7922.72. The vulnerability is classified with medium severity by Chromium security. No CVSS score is provided.
Potential Impact
If exploited, this vulnerability could allow an attacker who has already compromised the renderer process to escape the sandbox, potentially gaining higher privileges or broader access on the host system. This could increase the impact of an initial compromise by bypassing Chrome's security containment mechanisms. However, exploitation requires prior compromise of the renderer process, limiting the initial attack vector.
Mitigation Recommendations
A fixed version is available: users should update Google Chrome on Mac to version 151.0.7922.72 or later to remediate this vulnerability. No additional mitigation steps are indicated by the vendor advisory. Patch status is confirmed by the vendor advisory linked.
