Side-channel information leakage in WebAudio 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: Low)
AnalysisAI
Side-channel information leakage via the WebAudio API in Google Chrome prior to 150.0.7871.47 enables a remote attacker to extract cross-origin data from a victim's browser session through a crafted HTML page. The vulnerability abuses WebAudio's timing or spectral measurement capabilities to infer data that should be isolated by the Same-Origin Policy, exposing potentially sensitive cross-origin resources. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim be running Google Chrome prior to version 150.0.7871.47 and navigate to an attacker-controlled web page containing crafted JavaScript that uses the WebAudio API to perform side-channel timing measurements. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) scores 6.5 Medium, driven primarily by the High confidentiality impact from cross-origin data exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker establishes a malicious or compromised website and embeds JavaScript that leverages the WebAudio API to make precise timing or frequency measurements correlated with cross-origin resource fetches in the victim's browser. When a targeted user navigates to the page - via phishing, malicious advertisement, or a compromised link - the script runs silently, extracting inferred cross-origin data such as authentication state or resource existence on other domains. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released patch for this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
