CVE-2021-44140

Estado: ModificadaCrítica (9.1)—

Remote attackers may delete arbitrary files in a system hosting a JSPWiki instance, versions up to 2.11.0.M8, by using a carefuly crafted http request on logout, given that those files are reachable to the user running the JSPWiki instance. Apache JSPWiki users should upgrade to 2.11.0 or later.
