AI Analysis

Impact

A flaw in the Speech API within Google Chrome allows a remote attacker to craft an HTML page that bypasses the browser’s same‑origin policy. This represents a CWE‑346 vulnerability and permits the attacker to override the same‑origin restrictions that normally isolate resources, enabling access to content or data that would otherwise be restricted.

Affected Systems

The vulnerability exists in all Google Chrome desktop releases prior to version 150.0.7871.47. End users running any earlier build remain vulnerable until they update to the fixed release.

Risk and Exploitability

The EPSS score of less than 1% indicates a low probability that the vulnerability will be exploited, while the CVSS score of 9.6 marks it as highly impactful. The vulnerability is not listed in CISA KEV and no public exploits are cited in the CVE data. A remote attacker can host a malicious HTML page to trigger the bypass.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade to Chrome 150.0.7871.47 or later to receive the patched Speech API.
  • If immediate upgrade is not possible, disable the Speech API feature via enterprise policy or the browser’s experimental flags to prevent its use.
  • Deploy a Content Security Policy that limits access to same‑origin resources or restricts the use of the Speech API.
