Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Lucene.Net.Replicator versions 4.8.0-beta00005 through 4.8.0-beta00016 are vulnerable to unsafe deserialization of untrusted data. An attacker who can intercept traffic between a replication client and server, or control the target replication node URL, can supply a crafted JSON response that is deserialized as an attacker-chosen exception type, potentially leading to remote code execution or unauthorized access. Upgrade to version 4.8.0-beta00017, which fixes the issue.
