AI Analysis

Impact

This vulnerability stems from inadequate policy enforcement for SVG files in Google Chrome versions earlier than 151.0.7922.72. A crafted HTML page can cause the browser to load an SVG that references cross‑origin data, enabling an attacker to access sensitive information that should be isolated by the browser’s same‑origin policy.

Affected Systems

Google Chrome users on versions before 151.0.7922.72 are affected. The issue was fixed in Chrome 151.0.7922.72 and later releases.

Risk and Exploitability

The CVSS score of 4.3 indicates a low‑severity information‑disclosure flaw, and the EPSS score of less than 1% suggests a very low likelihood of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Attacks would require a victim to open a maliciously crafted HTML page that includes the vulnerable SVG, so the attack vector is client‑side exploitation via the browser.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Google Chrome to version 151.0.7922.72 or newer to apply the vendor patch.
  • If an upgrade cannot be performed immediately, consider disabling inline SVG rendering for untrusted content through browser flags or the "--disable-rendering-of-untrusted-objects" command line option.
  • Add security headers such as Content‑Security‑Policy (e.g., "default-src 'none'; img-src blob:; child-src 'none'") to prevent unintended cross‑origin requests and restrict SVG loading to trusted origins.
