CVE-2022-3474

Credential disclosure via unfiltered remote downloader qualifiers

Published Oct 26, 2022 · Updated Aug 3, 2024

Credential disclosure in Google Bazel before 3.7.2, 4.2.3, or 5.3.2 allows remote attackers to receive unrelated credentials. GrpcRemoteDownloader serializes every user-provided download credential as Remote Asset API qualifiers instead of filtering them to the requested URL's domain. Exploitation requires the experimental remote downloader option and a remote service that receives the request; exposed credentials can grant access to unrelated domains.
