Machine-written summary

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

LocalS3 (Maven package io.github.robothy:local-s3-rest) versions before 1.21 are affected by an XML External Entity (XXE) injection flaw in the XML parser used for multipart upload requests. An unauthenticated attacker who can send requests to the server can make it read local files and send their contents over outbound network connections. Upgrade to version 1.21, which is the fixed release.
