Impact

Inappropriate implementation of the QUIC protocol in Google Chrome on Android allows a remote attacker to leak cross‑origin data through a specially crafted HTML page. The flaw creates an information‑leak vector that can expose sensitive data belonging to a browsing user, potentially compromising privacy and data integrity without providing control over the device.

Affected Systems

Google Chrome on Android devices running versions prior to 151.0.7922.72. The vulnerability is tied to the Android implementation of the QUIC protocol and affects all users of the affected Chrome releases on mobile.

Risk and Exploitability

The CVSS score of 4.3 indicates a medium severity impact, while an EPSS score of less than 1% suggests a very low likelihood of exploitation at present. The vulnerability is not present in the CISA KEV catalog. Attackers would need to serve a maliciously crafted HTML page to the victim’s Chrome browser; no privileged access or elevated rights are required, and the exploit would remain within the browser context.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Google Chrome on Android to the latest stable version (151.0.7922.72 or newer) that includes the QUIC fix.
  • Maintain automatic updates to ensure the browser receives future security patches promptly.
  • On devices where an immediate update is not possible, restrict exposure to untrusted web content by implementing strong content‑security policies or isolating web views with sandboxing features.
