Chrome: Externally Controlled Reference to a Resource in Another Sphere

Published Updated By the CyberSecBulletin desk

CVE-2026-95376 is a high-severity externally controlled reference to a resource in another sphere vulnerability in Chrome from Google, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 154.0.8037.57 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 0.17% 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 154.0.8037.57 or a later version.
  2. Read the advisory on chromereleases.googleblog.com for workarounds and exact fixed builds.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
