Solr versions 1.3.0 to 1.4.1, 3.1.0 to 3.6.2 and 4.0.0 to 4.10.4 are vulnerable to an XML resource consumption attack (a.k.a. Lol Bomb) via it’s update handler.?By leveraging XML DOCTYPE and ENTITY type elements, the attacker can create a pattern that will expand when the server parses the XML causing OOMs.

https://issues.apache.org/jira/browse/SOLR-13750
https://www.openwall.com/lists/oss-security/2019/09/10/1
Upstream's fix (upgrading dependencies) suggests the issue is in libwoodstox-java:
https://issues.apache.org/jira/browse/SOLR-6830
May be related to the change in the 4.x series of libwoodstox-java to
disabling coalescing by default which can trigger large memory consumption
when parsing specially crafted XML data.
