Articles & Coverage 1
AnalysisAI
Privilege escalation in the Import and export users and customers WordPress plugin (versions 2.4.16 through before 2.5.2) lets an authenticated user who holds only the create_users capability assign administrator roles during a CSV import, enabling creation of new admin accounts or promotion of existing users. Publicly available exploit code exists, though there is no KEV confirmation of active exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated account holding the create_users capability but NOT promote_users - a non-default configuration typically produced by a role-editor/custom-role plugin that delegates user management to a non-administrator. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine privilege-escalation flaw that merits prompt patching but sits below the top tier because exploitation is gated on an unusual privilege prerequisite. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade the Import and export users and customers plugin to version 2.5.2 or later (vendor-released patch: 2.5.2). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress installations for the Import and export users and customers plugin and identify any running versions 2.4.16 through before 2.5.2; if internet-facing or business-critical, immediately update to version 2.5.2 or later and, where patching cannot be completed, temporarily disable the plugin's CSV import function or restrict access to trusted administrators; also audit roles that hold create_users without promote_users and remove create_users from any non-administrative role unless explicitly required. …
