Insufficient policy enforcement in Privacy in Google Chrome prior to 150.0.7871.47 allowed an attacker in a privileged network position to leak cross-origin data via malicious network traffic. (Chromium security severity: Low)
AnalysisAI
Cross-origin data leakage in Google Chrome prior to 150.0.7871.47 enables an on-path network adversary to bypass Chrome's privacy policy enforcement and observe data belonging to a different origin via crafted malicious network traffic. The flaw is classified as CWE-693 (Protection Mechanism Failure), indicating Chrome's privacy isolation layer fails to correctly enforce cross-origin restrictions under certain network conditions. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a privileged network position - specifically, the ability to inject or intercept network traffic between the victim's browser and the remote server (e.g., via ARP spoofing, rogue access point, BGP hijack, or ISP-level interception). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 4.3 (Medium) reflects a genuinely limited impact: C:L with no integrity or availability consequence, and UI:R constraining passive exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker operating a rogue wireless access point at a public venue, or positioned at the network edge via ARP poisoning on a corporate LAN, injects crafted HTTP or HTTPS-adjacent network responses while the victim browses normally in Chrome. The malicious traffic triggers Chrome's insufficient privacy policy enforcement, causing the browser to leak cross-origin response data - such as the contents of a framed resource or a cross-origin fetch - back to the attacker's vantage point. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, which is confirmed as the vendor-released patch per the Google Chrome Stable Channel Update advisory at chromereleases.googleblog.com. … Detailed patch versions, workarounds, and compensating controls in full report. |
