CVE-2026-87442: Google Chrome vulnerability

Q: Who is realistically exposed to this issue?

Users of Google Chrome versions earlier than 153.0.8010.36 are affected only in a scenario where the renderer process has already been compromised. The issue could then be used to potentially bypass the web origin policy.

Q: What does an attacker need to exploit this vulnerability?

The attacker needs to have compromised the Chrome renderer process and use a crafted HTML page. The available information does not indicate that this issue alone provides initial renderer compromise.

Q: What is the remediation?

Update Google Chrome to version 153.0.8010.36 or later. The provided information does not identify an alternative mitigation for systems that cannot be updated immediately.
