GHSA-wc53-4255-gw3f The XWiki JIRA extension allows data leak through an XXE attack by using a fake JIRA server

• Maven org.xwiki.contrib.jira:jira-macro-default: >= 4.2, < 8.5.6 → fixed in 8.5.6

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: ``` ]> ... &xxe; https://jira.xwiki.org/browse/XE-307 {RETIRED} XWiki Enterprise &xxe; ... ``` 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).
