Original description
KurrentDB is a database engineered for modern software applications and event-driven architectures. In version 26.1.0, a user authorized to read the $all stream can use Secondary Indexing query capabilities to read arbitrary files accessible to the database process, enumerate directories, and issue HTTP GET requests from that process. The default configuration limits this privilege to administrators. The flaw does not permit file writes and does not expose environment variables. This issue is fixed in version 26.1.1.
