CVE-2026-78943

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

Description Improper input validation in the editing component allows a remote attacker to bypass the web origin policy. This occurs when an attacker compromises the renderer process and uses social engineering to lure a user to a crafted HTML page. The web origin policy is a security mechanism that restricts how a document or script loaded from one origin can interact with a resource from another origin.

Recommendations Update Google Chrome to version 152.0.7977.65 or later.
