CVE-2022-3057Network attack vector

Cross-origin data leak via iframe sandbox flaw

Published Sep 26, 2022 · Updated May 21, 2025

Inappropriate iframe sandbox handling in Google Chrome before 105.0.5195.52 allows remote attackers to leak cross-origin data via crafted HTML. Public records identify the iframe Sandbox implementation as the affected locus but do not disclose the exact incorrect operation or validation failure. Exploitation requires a user to open attacker-crafted HTML, after which sandboxed content can expose data belonging to another origin.
