AnalysisAIv1 – Sep 15, 2026

Improper certificate validation in Chrome's Federated Credential Management (FedCM) component — fixed in Chrome 153.0.8010.36 — lets a remote attacker who controls crafted network traffic, combined with social engineering of the victim, bypass web origin policy and expose cross-origin identity data. The flaw is a confidentiality-only issue (no integrity or availability impact) and Chrome rates it security severity Low, despite a 7.5 CVSS base score; EPSS is only 0.15% (4th percentile), it is not in CISA KEV, and no public exploit code has been identified at time of analysis. Vendor-released patch: 153.0.8010.36.
