mediawiki: unable to change visibility of log entries when MediaWiki:Mainpage uses Special:MyLanguage
Published Dec 18, 2020

MEDIUMCVSS 3.1
EPSS 1.71%
Description
MediaWiki before 1.35.1 blocks legitimate attempts to hide log entries in some situations. If one sets MediaWiki:Mainpage to Special:MyLanguage/Main Page, visits a log entry on Special:Log, and toggles the "Change visibility of selected log entries" checkbox (or a tags checkbox) next to it, there is a redirection to the main page's action=historysubmit (instead of the desired behavior in which a revision-deletion form appears).
