Arbitrary read and write via Storage side channel

Published Nov 6, 2025 · Updated Nov 6, 2025

Side-channel information leakage in Google Chrome Storage before 141.0.7390.54 allows remote attackers to read or write arbitrary data. Google has not publicly disclosed how the Storage component creates the side channel or performs the out-of-bounds read mapped by CISA. A crafted HTML page reaches the flaw without authentication or further interaction, and the reported consequence is limited to arbitrary data access.
