CVE-2023-5850Network attack vector

Domain spoofing via crafted download origin

Published Nov 1, 2023 · Updated Feb 13, 2025

Incorrect security UI in Google Chrome before 119.0.6045.105 allows remote attackers to spoof a download's source domain. The Downloads interface renders a crafted long subdomain so that the displayed origin misrepresents the domain that supplied the file. Exploitation requires a user to initiate or inspect the attacker-controlled download; published Chrome material does not disclose the exact rendering or truncation error.
