UI misrepresentation in FedCM in Google Chrome prior to 153.0.8010.36 allowed a remote attacker leveraging social engineering to spoof UI elements via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
UI misrepresentation in Google Chrome's FedCM (Federated Credential Management) API prior to 153.0.8010.36 enables remote attackers to spoof identity-provider sign-in dialogs via crafted HTML pages, requiring user interaction. The flaw (CWE-451) allows a malicious page to manipulate how FedCM presents credential prompts, potentially misleading users into authorizing the wrong identity provider or disclosing credential context to an attacker-controlled endpoint. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) the victim is running Google Chrome prior to 153.0.8010.36; (2) the FedCM API is accessible in the browser context (it is enabled by default in Chrome); (3) the victim visits an attacker-controlled web page that invokes the FedCM sign-in dialog with crafted parameters; (4) the victim actively interacts with the spoofed dialog (UI:R - passive page load is insufficient). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world exploitation risk is limited by the UI:R requirement - a victim must visit a malicious page and interact with a FedCM dialog - making fully automated exploitation impossible. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: Chrome 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
