MITRE ATT&CK
2 techniques across 2 tactics: Collection, Discovery The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Access to Chrome network log file containing sensitive information. Requires attacker to obtain log files from target system running Google Chrome versions prior to 144.0.7559.59, typically through local file access, backup compromise, or log aggregation systems. |
| Impact | CVSS 9.8 — Chrome vulnerabilities affect billions of users. Network-positioned attacks are feasible on public WiFi, compromised routers, or through ISP-level interception. |
| Exploit ScenarioDerived | An attacker performing a man-in-the-middle attack on a public WiFi network exploits the insufficient policy enforcement to intercept or access data that Chrome should have protected through its security policies. |

Executive ViewAI
Organizations using Network in Google Chrome face critical risk from CVE-2026-0905, a information exposure vulnerability rated CVSS 9.8. This could expose sensitive information including credentials, configuration data, or user records to unauthorized parties.
