Machine-written summary

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

Plexus Archiver versions before 4.8.0 (Maven org.codehaus.plexus:plexus-archiver) are vulnerable to arbitrary file creation when extracting an untrusted archive. If an entry matches a symbolic link in the destination directory whose target does not exist, the extraction check can be bypassed and the entry's content is written to the link's target outside the intended directory. This could lead to remote code execution. Upgrade to version 4.8.0 or later.
