Cross-origin data disclosure via unvalidated network input
Published Jun 30, 2026 · Updated Jun 30, 2026
Input validation flaw in Google Chrome's Network component before 150.0.7871.47 allows remote attackers to leak cross-origin data via crafted HTML. The Network component insufficiently validates untrusted input from a compromised renderer; the exact field and validation failure remain restricted. Exploitation requires a compromised renderer and interaction with the crafted page; the documented consequence is cross-origin data disclosure only.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
