CVE-2026-11036 is a medium severity vulnerability in Google Chrome's DOM implementation before version 149.0.7827.53. It allows a remote attacker to bypass the same origin policy by crafting a malicious HTML page. The same origin policy is a critical security mechanism that restricts how documents or scripts loaded from one origin can interact with resources from another origin. This vulnerability could lead to integrity issues by enabling unauthorized script interactions across origins. The CVSS vector indicates the attack requires no privileges and user interaction is needed, with network attack vector and low attack complexity. There is no indication of known exploits in the wild. The vendor advisory linked does not explicitly state patch availability or remediation status.

The vulnerability allows bypassing the same origin policy, potentially enabling an attacker to perform unauthorized actions or script interactions across different web origins. This compromises the integrity of web content isolation but does not directly impact confidentiality or availability. Exploitation requires user interaction and can be performed remotely over the network.

Patch status is not yet confirmed — check the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html for current remediation guidance. Users and administrators should monitor for official updates from Google Chrome and apply them promptly once available. Until then, exercising caution with untrusted web content and limiting user interaction with suspicious pages is advisable.
