Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Goobi viewer (io.goobi.viewer:viewer-core, the Maven package) versions 4.8.0 through 26.04 are affected. The REST endpoint POST /api/v1/index/stream forwarded arbitrary Solr streaming expressions from unauthenticated network clients to the backend Solr server. An attacker could read the full Solr index, including access-restricted documents, and in default Solr deployments could also modify or delete indexed records. No fixed version is listed, but the endpoint has been removed in a later commit. Until an update is deployed, block the endpoint at a reverse proxy or in the Tomcat configuration.
