Origin-policy bypass via Variations input validation

Published Aug 25, 2026 · Updated Aug 27, 2026

Improper input validation in Google Chrome Variations before 152.0.7977.65 allows remote attackers to bypass web origin policy. The public record does not identify the malformed field or the validation operation that Variations performs incorrectly on untrusted network input. Exploitation requires Chrome to process crafted network traffic, and the disclosed consequence is limited to a web-origin-policy bypass.
