CVE-2025-31487: The XWiki JIRA extension allows data leak through an XXE attack by using a fake JIRA server
Impact If the JIRA macro is installed, any logged in XWiki user could edit his/her user profile wiki page and use that JIRA macro, specifying a fake JIRA URL that returns an XML specifying a DOCTYPE pointing to a local file on the XWiki server host and displaying that file's content in one of the returned JIRA fields (such as the summary or description for example).
For example:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE foo [ <!ENTITY xxe SYSTEM "file:///etc/passwd"> ]> <rss version="0.92"> ... <item> <title>&xxe;</title> <link>https://jira.xwiki.org/browse/XE-307</link> <project id="10222" key="XE">{RETIRED} XWiki Enterprise</project> <description>&xxe;</description> <environment/> ...
Patches The vulnerability has been patched in the JIRA Extension v8.6.5.
Workarounds No easy workaround except to upgrade (which is easy using the XWiki Extension Manager).
