Insufficient policy enforcement in SVG 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 SVG rendering subsystem (versions prior to 150.0.7871.47) allows remote attackers to exfiltrate sensitive information from other origins by directing victims to a crafted HTML page. The root cause is insufficient policy enforcement in SVG handling, classified as CWE-346 (Origin Validation Error), effectively bypassing Same-Origin Policy protections. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on any supported desktop platform with a version strictly below 150.0.7871.47. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N reflects a network-accessible, low-complexity attack requiring no attacker privileges but mandating user interaction - the victim must visit a crafted page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious HTML page embedding crafted SVG content engineered to trigger insufficient cross-origin policy enforcement in Chrome's SVG renderer. A victim running Chrome prior to 150.0.7871.47, lured via a phishing link or malicious advertisement, visits the page; the SVG payload silently reads sensitive cross-origin data - such as authentication tokens, session cookies, or page content - from a co-authenticated origin the victim has open in their browser. … |
| Remediation | Upgrade Google Chrome to version 150.0.7871.47 or later, as released in Google's stable channel update documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
