Inappropriate implementation in Autofill in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Cross-origin data leakage in Google Chrome's Autofill component prior to version 149.0.7827.53 enables remote attackers to exfiltrate sensitive data from other origins by enticing a victim to visit a crafted HTML page. Despite a CVSS score of 7.5 reflecting high confidentiality impact, the EPSS score of 0.03% and Chromium's own 'Low' severity rating indicate limited real-world risk, and no public exploit identified at time of analysis.

Technical ContextAI

The flaw resides in Chrome's Autofill subsystem, which stores and inserts user data (addresses, payment info, credentials) into web form fields. The vulnerability is classified under CWE-352 (Cross-Site Request Forgery), suggesting that the Autofill implementation does not adequately enforce the same-origin policy or anti-CSRF controls when handling data fills across origins. A crafted page can therefore coerce the browser into disclosing data tied to a different origin, breaking the web's fundamental isolation guarantee. The affected component is Chromium's browser-side Autofill module shipped in Google Chrome for desktop, as confirmed by the chromereleases.googleblog.com stable channel announcement.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 - upgrade desktop installations to this version or later via the built-in auto-updater or by restarting the browser after Chrome reports an update is ready, then verify via chrome://settings/help. Enterprises managing Chrome through Google Admin Console, group policy, or Workspace updater channels should confirm the stable channel pin is current and force-restart any long-running browser sessions, since the Autofill component cannot be selectively disabled without significantly degrading usability. Where immediate patching is not possible, a partial compensating control is to disable Autofill for addresses and payment methods under chrome://settings/autofill - this prevents cross-origin leakage of stored data at the cost of user convenience, but does not eliminate session-scoped autofill behavior.
