CVE-2023-28360Network attack vector

Download warning bypass via skipped danger check

Published May 11, 2023 · Updated Jan 27, 2025

Security warning bypass in Brave Browser before 1.48.171 allows attackers to deliver dangerous files without a safety prompt. The Brave override in download_target_determiner.cc treats prompting for a save location as a reason to skip the download danger check. A user must initiate the download with Ask where to save each file before downloading enabled; the result is a potentially dangerous file saved without the expected warning.
