Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim running Google Chrome prior to 151.0.7922.72 with the built-in Passwords/autofill feature active (default configuration) and at least one saved credential for a target origin stored in the browser. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page and socially engineers a target into visiting it while Chrome's password manager contains saved credentials for a victim origin. The attacker then induces the user to perform specific UI interactions - such as triggering autofill prompts or clicking crafted elements - causing the Passwords implementation to leak cross-origin data back to the attacker-controlled page. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, which resolves this vulnerability per the Chrome stable channel advisory at http://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
