Description
An issue was discovered in MediaWiki that allows JavaScript execution by staff/admin users who do not intentionally have the editsitejs capability. This is due to XSS in Wikibase date formatting via
wikibase-time-precision-* fields.Recommendations
For versions prior to 1.35.9, update to version 1.35.9 or later.
For versions 1.36.x through 1.38.x before 1.38.5, update to version 1.38.5 or later.
For versions 1.39.x before 1.39.1, update to version 1.39.1 or later.
As a temporary workaround, consider restricting access to the
wikibase-time-precision-* fields to minimize the risk of exploitation.Exploit
