CVE-2026-91718 is a use-after-free vulnerability in the Core component of Google Chrome that allows a remote attacker to execute arbitrary code outside the browser sandbox via a specially crafted HTML page. The flaw exists in Chrome versions prior to 153.0.8010.47 and is rated High severity by the Chromium security team. An attacker who successfully exploits this vulnerability gains the ability to run arbitrary code on the victim's system, potentially bypassing Chrome's sandbox protections. All users of Google Chrome who have not yet updated to version 153.0.8010.47 or later are affected. No public proof-of-concept or known in-the-wild exploitation has been reported at this time.

What to do: Update Google Chrome to version 153.0.8010.47 or later immediately via Chrome Settings > About Chrome. Enterprise administrators should verify that managed deployments are pulling the latest stable channel update and consider using Chrome's auto-update policies to enforce rapid patching. Monitor for any future reports of in-the-wild exploitation, as use-after-free flaws in Chrome are frequently weaponized once details become public.
