GHSA-c8wv-qwwc-6j73

MediaWiki allows a denial of service

Quick fix

GHSA-c8wv-qwwc-6j73 — mediawiki/core: upgrade to the fixed version with the command below.

composer require mediawiki/core:^1.36.2

Details

MediaWiki before 1.36.2 allows a denial of service (resource consumption because of lengthy query processing time). Visiting Special:Contributions can sometimes result in a long running SQL query because PoolCounter protection is mishandled.
