- Summary
- Stored XSS leads to privilege escalation in MediaWiki v1.40.0
- Details
-
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.
