An integer overflow in the Network module of Google Chrome before version 148.0.7778.96 enables a remote attacker, with control over the renderer process, to bypass the same origin policy through a crafted HTML page. This vulnerability could potentially allow unauthorized access to web resources that are normally restricted by same origin policy enforcement. The issue is classified as medium severity by Chromium security. The vendor advisory is available but does not explicitly state the patch or remediation status.

If exploited, this vulnerability allows bypassing the same origin policy, which is a fundamental security control in web browsers. This could lead to unauthorized access to sensitive data or cross-origin interactions that violate security boundaries. However, exploitation requires prior compromise of the renderer process, limiting the attack surface. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html for current remediation guidance. Since this affects a client application, users should update to the latest Chrome version once a fix is officially released. Until then, no specific mitigations are provided by the vendor.
