The issue affects all versions of the WP eMember plugin up to version 10.2.2, making it a concern for users utilizing this plugin on their WordPress sites.
The severity of this vulnerability is classified as medium, with a CVSS score of 5.3. This classification indicates a moderate risk to organizations, particularly those that have not implemented proper access controls. The potential for exploitation through network access, combined with low attack complexity, means that organizations should take this threat seriously.
Risk to organizations includes unauthorized access to sensitive information, which can lead to further exploitation or data breaches. Given the nature of the vulnerability, attackers may leverage it to gain insights into user data or perform actions that they should not be permitted to execute. Organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits available for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant and monitor their systems for any signs of unauthorized access or exploitation attempts.
Vulnerability Details
The CVE description states that this vulnerability allows exploitation of incorrectly configured access control security levels in the WP eMember plugin. The vulnerability falls under the CWE-862 classification, indicating a missing authorization issue. The vulnerability was publicly disclosed on March 19, 2026.
The CVSS score of 5.3 signifies a medium severity level, suggesting that while the risk is present, it is not classified as critical. The attack vector is categorized as network-based, with low complexity and no privileges required to exploit the vulnerability. Additionally, no user interaction is necessary for exploitation.
Technical Analysis
The root cause of this vulnerability is the inadequate implementation of access controls in the WP eMember plugin. This oversight allows attackers to bypass authorization checks that are meant to restrict access to sensitive functionalities within the plugin.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without needing physical access to the server. The attack complexity is rated as low, indicating that minimal skills are required to execute an attack. Additionally, no privileges are required to exploit this vulnerability, which increases the risk profile.
The impact on confidentiality is rated as low, while integrity and availability impacts are marked as none. This means that while the attacker may gain unauthorized access, the overall functionality and data integrity of the system are not compromised.
Risk & Impact Analysis
The potential risks associated with this vulnerability are significant. Organizations deploying the WP eMember plugin could face unauthorized access to sensitive user data or administrative controls, leading to privacy violations and potential data breaches. The blast radius could extend to any organization utilizing the affected plugin, thereby increasing the urgency for remediation.
Given the CVSS score of 5.3, organizations should address this vulnerability in their priority patch cycle. Even though it is not classified as critical, the risk of exploitation remains, and the presence of such vulnerabilities can lead to a cumulative effect on security posture.
