Chrome: Authentication Bypass by Spoofing

Published Updated By the CyberSecBulletin desk

CVE-2025-11209 is a high-severity authentication bypass by spoofing vulnerability in Chrome from Google, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 141.0.7390.54 as the first without the flaw, so updating Chrome to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Chrome to 141.0.7390.54 or a later version.
  2. Read the advisory on chromereleases.googleblog.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
