Description Dhananjay Arunesh 2020-12-02 18:22:10 UTC 
An issue was discovered in MediaWiki 1.32.x through 1.34.x before 1.34.4. LogEventList::getFiltersDesc is insecurely using message text to build options names for an HTML multi-select field. The relevant code should use escaped() instead of text().

Comment 5 Przemyslaw Roguski 2020-12-07 16:50:22 UTC 
Statement:

OpenShift Container Platform (OCP) delivers the mediawiki package, but the vulnerable code is not bundled, therefore OCP is not affected by this flaw.
