CVE-2023-0481

Local information disclosure via world-readable temporary files

Published Feb 24, 2023 · Updated Mar 12, 2025

Information disclosure in RESTEasy Reactive in Red Hat Quarkus allows local users to read temporary request-body files. FileBodyHandler passes request bodies to File.createTempFile(), which creates files with mode 0644 instead of an owner-only mode. A low-privileged local account can read request-body contents while the temporary file remains present; integrity and availability are unaffected.
