WP User Manager: Improper access control
No attacker login is required by the supplied CVSS vector. A caller can reach a protected operation without the intended permission check. The vector reports limited confidentiality impact, limited integrity impact and no victim interaction. The protected operation, resource and resulting state change or exposed data are undisclosed. The privilege-abuse classification does not establish administrator account creation or a particular privilege-escalation path. The authoritative export does not identify the vulnerable endpoint, action, parameter or function, so the exact input-to-operation path cannot be established from this record. Affected versions: <= 2.9.20. The authoritative export identifies 2.9.21 as fixed for this CVE.

- Oct 05, 2026
This CVE was published Oct 05, 2026 and is one of 17 known issues for this plugin.
Update, patch or deactivate.
Update WP User Manager to 2.9.21 or a later supported release. An application-level fix should address the following: Enforce the intended capability and object-level permission server-side before accessing or changing the protected resource. A nonce or caller-supplied identifier alone is not an authorization check.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
