Side-channel information leakage in Scroll in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Side-channel information leakage via Chrome's Scroll implementation exposes cross-origin data to remote attackers who can lure a victim to a crafted HTML page. All Chrome versions prior to 150.0.7871.47 are affected; exploitation requires user interaction (visiting the attacker-controlled page) but no authentication. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required: the victim must visit an attacker-controlled HTML page in an affected Chrome version (prior to 150.0.7871.47). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 3.1 score of 6.5 (Medium) reflects a network-reachable, low-complexity attack requiring only one user interaction, with High confidentiality impact and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that embeds or references a cross-origin resource and then manipulates scroll behavior to infer properties of that resource through observable side-channel differences in the browser's rendering engine. The victim is social-engineered into visiting the attacker's page, after which the attacker's JavaScript silently exfiltrates cross-origin data (e.g., authenticated page content, sensitive URL fragments) back to the attacker-controlled server. … |
| Remediation | Vendor-released patch: Chrome 150.0.7871.47. … Detailed patch versions, workarounds, and compensating controls in full report. |
