AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N
Renderer-process compromise is a hard prerequisite raising AC to H; confidentiality impact is partial (cross-origin data leak only), no integrity or availability impact.

Insufficient validation of untrusted input in Network in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Cross-origin data leakage in Google Chrome's Network component (versions prior to 150.0.7871.47) enables a remote attacker who has already compromised the renderer process to exfiltrate cross-origin data via a specially crafted HTML page. This is a chained vulnerability - renderer-process compromise is a hard prerequisite, meaning real-world risk is substantially lower than the network-accessible CVSS vector implies. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two conditions to both be satisfied: first, the attacker must have already achieved code execution within Chrome's renderer process - this is a non-trivial precondition requiring a separate renderer-level vulnerability (e.g., a memory corruption or logic flaw in V8 or Blink); second, the user must interact with a crafted HTML page (UI:R per the CVSS vector), meaning the victim must visit an attacker-controlled or compromised site during the attack window. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS score of 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) captures the web-facing exposure but materially understates the attack complexity by omitting the renderer-process compromise prerequisite from the AC and PR metrics. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate renderer-process vulnerability (e.g., a V8 type confusion bug) via a malicious webpage to gain code execution inside Chrome's renderer sandbox. With renderer control established, the attacker serves a crafted HTML page that triggers the insufficient Network-layer input validation to read and exfiltrate data from a cross-origin context - for example, session tokens or page content from a banking site open in another tab. … |
| Remediation | The vendor-released patch is Google Chrome 150.0.7871.47, available via the stable channel update announced at chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
