CVE-2025-31487

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).

Root Cause Analysis

The vulnerability is an XXE attack in the JIRA macro's XML processing. The key vulnerable function is createSAXBuilder() in HTTPJIRAFetcher class, which was modified in both commits to add XXE protection. The first commit (98a74c2) added basic protection by setting ACCESS_EXTERNAL_DTD and ACCESS_EXTERNAL_SCHEMA to empty strings, while the second commit (5049e35) implemented stronger protection by completely disabling DTD processing. The function is clearly involved in processing potentially malicious XML input from a fake JIRA server, making it the primary vulnerable function that would appear in a runtime profiler during exploitation.
