Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
LocalS3 (Maven io.github.robothy:local-s3-rest) versions before 1.21 are vulnerable to XML external entity injection through the bucket tagging API. An unauthenticated attacker who can send requests to the service can define external entities in the tagging XML and read arbitrary files the application can access on the server. Upgrade to version 1.21, which contains a fix.
