Impact

Inappropriate implementation in Google Chrome’s Password Manager prior to version 149.0.7827.53 enables a remote attacker to leak cross‑origin data via a crafted HTML page. The flaw allows the attacker to read data that was previously inaccessible between origins, potentially exposing sensitive information stored locally by the browser.

Affected Systems

Google Chrome builds before 149.0.7827.53 on all platforms are affected; users running any earlier stable channel version remain susceptible until the issue is addressed.

Risk and Exploitability

Chromium’s security team rated the vulnerability as medium severity with a CVSS score of 6.5 and an EPSS score of < 1%. The flaw can be exploited remotely by serving a malicious web page to a user’s browser, causing the leak of cross‑origin data. The vulnerability is not listed in CISA’s KEV catalog and no public exploits have been reported, yet its remote nature and the potential for data exposure justify prompt action.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Chrome to version 149.0.7827.53 or later, which includes a fix that addresses the password‑manager information‑exposure flaw.
  • Configure the browser’s privacy settings to enforce strict same‑origin policies and disable cross‑site data sharing, mitigating the missing access control weakness (CWE‑346).
  • Remove or disable any extensions that request extensive credentials or data‑access permissions, reducing the risk of CSRF‑like privilege escalation (CWE‑352).
  • Consider temporarily disabling the Password Manager feature or restricting its use until the official update is available, limiting potential data leakage.
