Description Srikanth Balasubramanian 2026-08-12 14:24:51 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Insufficient validation of untrusted input in Workers in Google Chrome prior to 151.0.7922.109 allowed a remote attacker who had compromised the renderer process to bypass site isolation via a crafted HTML page. (Chromium security severity: High)
