Descriptions
In MediaWiki before 1.31.15, 1.32.x through 1.35.x before 1.35.3, and 1.36.x before 1.36.1, bots have certain unintended API access. When a bot account has a "sitewide block" applied, it is able to still "purge" pages through the MediaWiki Action API (which a "sitewide block" should have prevented).
En MediaWiki versiones anteriores a 1.31.15, versiones 1.32.x hasta 1.35.x, versiones anteriores a 1.35.3, y versiones 1.36.x anteriores a 1.36.1, unos bots presentan determinados accesos a la API no deseados. Cuando una cuenta de bot presenta un "sitewide block" aplicado, es capaz de "purge" páginas mediante la API de acción de MediaWiki (lo que un "bloqueo del sitio" debería haber impedido)
