CVE-2026-78947

Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 152.0.7977.65

Description Incomplete cleanup in Chromium allows a remote attacker to bypass the web origin policy, which is a security mechanism that restricts how a document or script loaded from one origin can interact with a resource from another origin. This bypass can be achieved through the use of a crafted Chrome extension and social engineering.

Recommendations Update Google Chrome to version 152.0.7977.65 or later.
