Inappropriate implementation in Skia in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin data leakage in Google Chrome's Skia graphics library (all versions prior to 151.0.7922.72) enables a remote attacker who has already achieved renderer process compromise to exfiltrate cross-origin data via a crafted HTML page. The flaw is a CWE-346 Origin Validation Error within Skia's rendering pipeline and is constrained to an information-disclosure impact with no integrity or availability consequence. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have already compromised the Chrome renderer process through a separate, prior vulnerability - this is explicitly stated in the CVE description and is the dominant constraint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.1 (Low) is consistent across all available signals. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A sophisticated attacker who has already exploited a separate, unrelated renderer-level vulnerability in Chrome delivers a crafted HTML page to the victim, triggering the Skia Origin Validation Error to read and leak data from a cross-origin context loaded in the same browser session - such as authentication tokens or page content from a banking or enterprise web application. No public exploit or proof-of-concept code has been identified at time of analysis, and the multi-stage nature of this attack makes opportunistic or mass exploitation unlikely. |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later; this is the vendor-confirmed patched release per the Stable Channel 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. |
