CVE-2026-78980

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

Description Improper input validation in ReaderMode allows a remote attacker to bypass the web origin policy—a security mechanism that restricts how a document or script loaded from one origin can interact with a resource from another origin—into a privileged page. This is achieved by leveraging social engineering and a crafted HTML page.

Recommendations Update Google Chrome to version 152.0.7977.65 or later.
