DSpace < 3.6, 4.0-4.5 - Path Traversal via XMLUI Themes Path
The XMLUI feature in DSpace before 3.6, 4.x before 4.5, and 5.x before 5.5 allows directory traversal via the themes/ path in an attack with two or more arbitrary characters and a colon before a pathname, as demonstrated by a themes/Reference/aa:etc/passwd URI.
