CVE-2024-47884

Local Firefox history disclosure via copied permissions

Published Oct 11, 2024 · Updated Sep 2, 2025

Information disclosure in zefr0x foxmarks 2.0.3 and earlier allows local users to read Firefox browsing data from a temporary file. DataBase::get_temp_database uses std::fs::copy to duplicate places.sqlite into a NamedTempFile under /tmp, replacing its 0600 mode with source permissions that can be 0644. A second local account can read the copy only while the targeted user runs the bookmarks or history command, exposing stored URLs and usage metadata.
