CVE-2026-120554
The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.5.11 This is due to a non-atomic multi-option write sequence in the ACUICron::savesettings() function, which persists acuicronactivated, acuicronconfiguredby, acuicronuserid, and acuicronpathtofile before reaching the authorization gate that calls wpdie() when a non-promoter submits a role. This makes it possible for authenticated attackers holding a custom delegated role with createusers but without promoteusers or editusers to escalate their privileges to Administrator, provided a prior administrator cron-tab save exists and no successful save intervenes before the next unattended cron tick processes the attacker's repointed CSV file.
