CVE-2026-92415Network attack vectorHinoki check available

File creation or truncation via client-side unsafe reflection

Published Oct 7, 2026 · Updated Oct 7, 2026

Unsafe reflection in Apache Jackrabbit's WebDAV client allows remote attackers to create or truncate files via malicious repository responses. The jackrabbit-spi2dav client treats server-provided class names as instructions to instantiate classes from the application's classpath. Exploitation requires an application using jackrabbit-spi2dav, directly or through jackrabbit-jcr2dav, to contact a malicious repository or accept an intercepted response; Jackrabbit servers are unaffected.
