CVE-2024-8912Network attack vector

Response interception via crafted HTTP request headers

Published Oct 11, 2024 · Updated Oct 11, 2024

HTTP request smuggling in Google Cloud Looker allows remote attackers to intercept HTTP responses intended for legitimate users. Looker accepts crafted HTTP request headers that cause inconsistent request interpretation, but Google has not disclosed the parsing locus or configuration details. Exploitation requires certain unspecified configurations and exposes response contents, which can include sensitive information; Looker original hosted instances were not affected.
