Impact

The vulnerability stems from an observable discrepancy in the rendering of SVG elements in Google Chrome versions before 152.0.7977.65, which allowed a remote attacker to retrieve data from a different origin by serving a specially crafted HTML page.

Affected Systems

Current Chrome releases are affected, specifically any Chrome desktop edition prior to 152.0.7977.65. The patch is included in the stable channel update released on August 5, 2026, bringing the browser to version 152.0.7977.65.

Risk and Exploitability

The CVSS score for this vulnerability is 4.3, indicating a medium severity impact. The EPSS score remains below 1%, suggesting a low likelihood of exploitation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Chrome to the latest stable release (152.0.7977.65 or newer).
  • If an immediate upgrade is not feasible, configure a Content Security Policy that restricts loading of SVG content from untrusted origins, for example by setting `default-src 'self'` and blocking `svg-src`.
  • Maintain a regular update routine for all web browsers and avoid visiting unfamiliar sites that may host malicious SVG fragments.
