A user able to attach a file to a page can post a malformed TAR file by manipulating file modification times headers, which when parsed by Tika, could cause a denial of service issue via CPU consumption.
This vulnerability has been patched in XWiki 14.10.18, 15.5.3 and 15.8 RC1.
The workaround is to download commons-compress 1.24 and replace the one located in XWiki WEB-INF/lib/ folder.
