Missing authorization in LocalNetworkAccess in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process to bypass system access restrictions via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
LocalNetworkAccess missing authorization in Google Chrome before 153.0.8010.36 allows a renderer-compromised attacker to bypass Chrome's Private Network Access (PNA) restrictions via a crafted HTML page, enabling unauthorized requests to private network resources. This is a chained second-stage capability (CWE-862): the attacker must already control the renderer process before this bypass is reachable. …

Vulnerability AssessmentAI
| Exploitation | Two concrete conditions must both be satisfied: (1) the attacker must have already compromised the Chrome renderer process via a separate, unrelated vulnerability - this is the primary and high-bar prerequisite explicitly stated in the CVE description; (2) the victim must visit a crafted HTML page (UI:R), which is typically the delivery mechanism for the upstream renderer exploit as well. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) and Chromium's own 'Medium' severity rating are in agreement - no severity-tier discrepancy. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
