CVE-2026-24570 identifies a missing authorization vulnerability in WisdmLabs Edwiser Bridge, a WordPress plugin that integrates Moodle LMS with WordPress sites. The flaw arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to access or manipulate resources beyond their authorization scope. The vulnerability affects all versions up to and including 4.3.2. The CVSS 3.1 base score is 5.4 (medium), reflecting a network attack vector (AV:N), low attack complexity (AC:L), privileges required at a low level (PR:L), no user interaction (UI:N), unchanged scope (S:U), and limited confidentiality and integrity impacts (C:L, I:L), with no impact on availability (A:N). Exploitation could lead to unauthorized data disclosure or modification within the Edwiser Bridge context, potentially exposing sensitive educational data or disrupting LMS integration integrity. No public exploits are currently known, but the vulnerability’s presence in a widely used LMS integration plugin poses a moderate risk. The lack of patches at the time of disclosure necessitates immediate attention to access control configurations and monitoring.

For European organizations, especially educational institutions relying on Moodle and WordPress integrations via Edwiser Bridge, this vulnerability could lead to unauthorized access to sensitive student or institutional data, undermining confidentiality and data integrity. While availability is not impacted, the exposure of educational records or manipulation of LMS data could result in compliance violations with GDPR and damage institutional reputation. The medium severity and network exploitability mean attackers could remotely leverage this flaw with minimal complexity, increasing risk in environments with multiple users having low-level privileges. The impact is particularly significant for organizations with large user bases and complex role assignments, where misconfigurations are more likely. Additionally, the absence of known exploits provides a window for proactive mitigation before active exploitation occurs.

Organizations should immediately review and tighten access control settings within Edwiser Bridge, ensuring that user roles and permissions are correctly configured to prevent unauthorized access. Until an official patch is released, consider restricting network access to the plugin’s endpoints to trusted IP ranges or internal networks. Implement detailed logging and monitoring of Edwiser Bridge activities to detect anomalous access patterns. Conduct regular audits of user privileges, especially for accounts with low-level access, to minimize the attack surface. Engage with WisdmLabs for updates and apply patches promptly once available. Additionally, consider deploying web application firewalls (WAFs) with custom rules to block suspicious requests targeting Edwiser Bridge endpoints. Educate administrators on the risks of misconfigured access controls and enforce the principle of least privilege across LMS integrations.
