Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of the Maven package dnsjava:dnsjava before 3.6.0 are affected. A network attacker, or a rogue recursive resolver, can add or replace records in DNS responses, including records from other zones, and applications that filter results only by record type may treat them as authentic. This can lead to credential redirection, mail misdirection, or manipulated trust anchors. Upgrade to dnsjava 3.6.0 or later.
