In this episode, we break down the recently discovered and actively exploited Chrome vulnerability CVE-2025-4664—a high-severity flaw stemming from insufficient policy enforcement in Chrome’s Loader component. This vulnerability allows attackers to leak cross-origin data, including sensitive query parameters and session information, via crafted HTML pages. Even more alarming: it's not limited to Chrome. Other Chromium-based browsers like Microsoft Edge, Brave, Opera, and Vivaldi are also at risk.

We’ll explore the technical mechanism behind the flaw, how it abuses Link headers and referrer-policy directives, and why it's capable of bypassing same-origin protections, putting OAuth-based login flows and session security at risk. With confirmed active exploitation, CVE-2025-4664 has been added to CISA’s Known Exploited Vulnerabilities Catalog, triggering federal mandates to patch or discontinue use of vulnerable versions before June 5, 2025.
