CVE-2026-8021: Script injection in Google Chrome
Script injection in UI in Google Chrome prior to 148.0.7778.96 allowed a remote attacker who convinced a user to engage in specific UI gestures to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: Low)
AI Analysis
Technical Summary
This vulnerability involves a cross-site scripting (UXSS) flaw in Google Chrome's UI that permits script or HTML injection when a user interacts with a maliciously crafted page using certain UI gestures. It affects Chrome versions before 148.0.7778.96. The issue was publicly disclosed with low severity and no known exploits in the wild. The vendor advisory linked is a general stable channel update announcement without explicit mention of a fix for this vulnerability.
Potential Impact
An attacker who successfully exploits this vulnerability can inject arbitrary scripts or HTML into the Chrome UI, potentially leading to UI spoofing or other low-severity impacts. However, exploitation requires user interaction with specific UI gestures on a crafted page. There are no known exploits in the wild, and the impact is considered low severity by the Chromium security team.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The linked Google Chrome stable channel update announcement does not explicitly confirm a fix for this vulnerability. Users should update to the latest Chrome version once a patch is confirmed available. Until then, exercise caution with untrusted web content and avoid engaging in unusual UI gestures on suspicious pages.
