CVE-2021-41800: Allocation of Resources Without Limits or Throttling

May 24, 2022 (updated February 1, 2024)

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.
