That report described potential cross-origin data exposure. Its suggested Chrome version threshold dates from May 2025 and is no longer suitable as current patch guidance. Update Chrome using its built-in updater, then check the installed version against Google’s current release notes or your organization’s browser policy.
What the Chrome security warning means
HotHardware’s May 16, 2025 report identified the flaw as CVE-2025-4664 and said it affected the Chromium Loader. It described a risk of cross-origin data leakage, meaning information could potentially be exposed across website boundaries. That is a reported risk, not evidence that passwords, payment details, addresses, or other specific information were actually stolen.
The report linked the warning to CISA’s Known Exploited Vulnerabilities catalog. CISA’s page, titled CISA Adds Three Known Exploited Vulnerabilities to Catalog, is dated May 15, 2025; the page content was not available to independently confirm its technical details here. The active-exploitation claim should therefore be understood as what the HotHardware report said, rather than as a newly verified status for October 2026.

Which Chrome version fixes the flaw?
The May 2025 report advised users to run a version newer than 136.0.7103.113. That is historical guidance, not a current October 2026 minimum. A version number only makes sense alongside its release date and platform; use the current Chrome update check and official release information rather than relying on that old threshold.

What if you use another Chromium-based browser?
The HotHardware report generalized the concern to Chromium-based browsers, but the available vendor advisories were not verified here. Do not assume every browser built on Chromium has the same affected versions or fix. Check the browser maker’s own security advisory and update channel, then install the current supported update for that browser and operating system.

If Chrome is managed by an employer, school, or other organization, updates may be controlled centrally. Follow the administrator’s browser-update policy and report a browser that remains behind the required version. Avoid bypassing management controls; administrators can confirm the approved version and deployment status for the device.
