CVE-2025-12183: LZ4 Java Compression has Out-of-bounds memory operations which can cause DoS

November 28, 2025 (updated December 3, 2025)

Out-of-bounds memory operations in org.lz4:lz4-java 1.8.0 and earlier allow remote attackers to cause denial of service and read adjacent memory via untrusted compressed input.

This is fixed in a forked release: at.yawk.lz4:lz4-java version 1.8.1. The original project has been archived: https://github.com/lz4/lz4-java, and Sonatype has added a redirect from org.lz4:lz4-java:1.8.1 to the new group ID.
