CVE-2026-27983 identifies an Incorrect Privilege Assignment vulnerability in the designthemes LMS Elementor Pro WordPress plugin, affecting versions up to and including 1.0.4. This vulnerability allows attackers with limited privileges to escalate their permissions, potentially gaining administrative control within the LMS environment. The root cause is improper privilege assignment or enforcement, which could allow unauthorized users to perform actions reserved for higher-privileged roles. The plugin is designed to integrate with Elementor Pro to provide learning management system capabilities on WordPress sites, commonly used by educational institutions and online course providers. Although no public exploits have been reported, the vulnerability's nature suggests that an attacker with authenticated access could leverage it to compromise the integrity and confidentiality of the LMS data and functionality. No patches or mitigation details have been published yet, but the issue was reserved and published in early 2026 by Patchstack. The vulnerability does not require user interaction beyond initial access, increasing its risk profile. The absence of a CVSS score means severity must be inferred from the potential impact on access control and system integrity.

The primary impact of this vulnerability is unauthorized privilege escalation within the LMS Elementor Pro plugin environment. An attacker exploiting this flaw could gain administrative privileges, allowing them to modify course content, access sensitive student data, alter user roles, or disrupt LMS operations. This could lead to data breaches, loss of data integrity, and disruption of educational services. Organizations relying on this plugin for critical learning management functions may face operational downtime and reputational damage. The vulnerability could also be leveraged as a foothold for further attacks on the underlying WordPress infrastructure or connected systems. Since LMS platforms often contain personal and academic data, the confidentiality impact is significant. The ease of exploitation is moderate, requiring some initial access but no additional user interaction, which broadens the scope of potential attackers. The lack of known exploits suggests limited current active threat but does not diminish the risk if weaponized in the future.

Organizations should immediately audit user roles and permissions within their LMS Elementor Pro installations to ensure the principle of least privilege is enforced. Restrict administrative access to trusted personnel only and monitor for unusual privilege escalations or account behavior. Implement strong authentication mechanisms, such as multi-factor authentication, to reduce the risk of initial access by attackers. Regularly back up LMS data to enable recovery in case of compromise. Stay alert for official patches or updates from designthemes and apply them promptly once available. In the interim, consider disabling or limiting the use of LMS Elementor Pro if feasible, or isolate the plugin environment to reduce exposure. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious privilege escalation attempts. Conduct penetration testing focused on privilege boundaries within the LMS environment to identify and remediate related weaknesses.
