Insufficient policy enforcement in Canvas 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
Cross-origin data leakage in Google Chrome's Canvas component prior to version 150.0.7871.47 exposes sensitive cross-origin content to remote attackers via a crafted HTML page. The flaw bypasses Same-Origin Policy protections enforced at the Canvas API layer, enabling pixel-level or structured data extraction from cross-origin resources rendered in a canvas context. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively visit or be redirected to a crafted HTML page controlled by the attacker - user interaction is required (CVSS UI:R), meaning passive network interception is not sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS base score of 6.5 reflects a Medium-severity confidentiality-only flaw with 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 containing JavaScript that draws a cross-origin image or resource into a Canvas element and exploits the policy enforcement gap to call getImageData() or toDataURL() to extract pixel data that would normally be blocked. A victim is socially engineered or redirected to this page - for example, via a phishing link or malicious advertisement - and upon page load, their browser silently leaks cross-origin content (such as authenticated profile images or rendered iframe content from a logged-in session) back to the attacker's server. … |
| Remediation | The primary fix is upgrading Google Chrome to version 150.0.7871.47 or later, confirmed as the patched release via the Chrome Stable Channel Update advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
