▼CVE Numbering Authority (CNA)
Stored XSS leads to privilege escalation in MediaWiki v1.40.0

Mediawiki v1.40.0 does not validate namespaces used in XML files. Therefore, if the instance administrator allows XML file uploads, a remote attacker with a low-privileged user account can use this exploit to become an administrator by sending a malicious link to the instance administrator.
