Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
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.
### Patches
This vulnerability has been patched in XWiki 14.10.18, 15.5.3 and 15.8 RC1.
### Workarounds
The workaround is to download [commons-compress 1.24](https://search.maven.org/remotecontent?filepath=org/apache/commons/commons-compress/1.24.0/commons-compress-1.24.0.jar) and replace the one located in XWiki `WEB-INF/lib/` folder.
