CVE-2024-8853

Estado: AnalizadaCrítica (9.8)—

The Webo-facto plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.40 due to insufficient restriction on the 'doSsoAuthentification' function. This makes it possible for unauthenticated attackers to make themselves administrators by registering with a username that contains '-wfuser'.
