Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Ignite (org.apache.ignite:ignite-core) versions 2.0.0 through 2.17.0 are vulnerable to relative path traversal in the REST API. An authenticated REST API user can use the "cmd=log" command with a crafted log path to read arbitrary files on the server. Upgrade to version 2.18.0, which fixes the issue.
