Side-channel information leakage in Media in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Side-channel information leakage in Google Chrome's Media component (versions prior to 151.0.7922.72) enables remote attackers to exfiltrate cross-origin data by luring a victim to a crafted HTML page that exploits observable timing or state signals in media processing. This bypasses the browser's Same-Origin Policy protections, allowing an attacker's origin to infer sensitive data loaded from a different origin. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim user running a vulnerable version of Google Chrome (prior to 151.0.7922.72) to visit an attacker-controlled HTML page containing crafted media content (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N, score 4.3) reflects a moderate, remotely exploitable flaw with low attack complexity and no attacker-side authentication requirement, but bounded by a requirement for user interaction and limited to low confidentiality impact with no integrity or availability loss. … 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 media resources from a victim's authenticated origin - for example, a private image or audio file accessible only when the victim is logged in to a target service. When the victim visits the attacker's page, Chrome's Media component leaks observable side-channel signals (such as load timing differentials) that the attacker's JavaScript measures to infer the content or state of the cross-origin resource. … |
| Remediation | The primary remediation is to update Google Chrome to version 151.0.7922.72 or later, which contains the vendor-released patch; details are published in the Chrome stable channel update advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
