CVE-2025-62087 identifies a Missing Authorization vulnerability (CWE-862) in the Web Builder 143 Sticky Notes plugin for the WordPress Dashboard, specifically affecting versions up to 1.2.4. This vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to access or perform actions beyond their authorization scope. The vulnerability is remotely exploitable over the network (AV:N) without requiring user interaction (UI:N), which means an attacker with some authenticated access can leverage this flaw to gain unauthorized read access to certain data or functionalities within the plugin. The CVSS v3.1 base score of 4.3 (medium severity) reflects that the impact is limited to confidentiality loss (C:L), with no impact on integrity (I:N) or availability (A:N). The scope remains unchanged (S:U), indicating the vulnerability affects only the vulnerable component without impacting other system components. No patches or fixes have been released at the time of publication, and there are no known exploits in the wild. The vulnerability was reserved and published in late 2025, highlighting a need for timely remediation. The plugin is used within WordPress dashboards to provide sticky note functionality, which may contain sensitive administrative or operational information. Exploitation could lead to unauthorized disclosure of such notes or related data, potentially exposing internal communications or operational details. Since the vulnerability requires some level of privilege, attackers would need to have at least limited authenticated access to the WordPress dashboard, which might be obtained via other means or insider threats. The lack of user interaction requirement facilitates automated exploitation once access is gained. Overall, this vulnerability represents a moderate risk to confidentiality within affected WordPress environments.

For European organizations, the primary impact of CVE-2025-62087 is the unauthorized disclosure of potentially sensitive information stored within the Sticky Notes plugin on WordPress dashboards. This could include internal notes, operational details, or other confidential data used by administrators or staff. While the vulnerability does not allow modification or deletion of data, the confidentiality breach could aid attackers in reconnaissance or further attacks. Organizations relying heavily on WordPress for internal portals, intranets, or administrative dashboards may face increased risk if this plugin is installed and accessible. The medium severity score reflects that while the impact is not critical, it can still lead to information leakage that may violate data protection regulations such as GDPR if personal or sensitive data is exposed. Additionally, attackers with limited privileges could escalate their knowledge of the environment, potentially facilitating lateral movement or privilege escalation. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as the vulnerability is publicly known. European entities with strict compliance requirements should prioritize assessment and mitigation to avoid regulatory penalties and reputational damage.

1. Immediate assessment: Identify all WordPress instances within the organization and inventory installed plugins to determine if Sticky Notes for WP Dashboard is in use and which versions are deployed. 2. Access control review: Restrict WordPress dashboard access to trusted users only, enforcing strong authentication mechanisms such as MFA to reduce the risk of unauthorized access. 3. Principle of least privilege: Limit user roles and permissions within WordPress to the minimum necessary, preventing users with limited privileges from accessing sensitive plugins or functionalities. 4. Network segmentation: Isolate administrative WordPress dashboards from public networks or untrusted segments to reduce exposure to remote exploitation. 5. Monitoring and logging: Enable detailed logging of WordPress dashboard activities and monitor for unusual access patterns or attempts to exploit the plugin. 6. Temporary disabling: If feasible, disable or uninstall the Sticky Notes plugin until a vendor patch or update is available. 7. Vendor engagement: Monitor Web Builder 143 communications for patch releases or security advisories and apply updates promptly once available. 8. Incident response readiness: Prepare to investigate and respond to any signs of exploitation, including unauthorized data access or suspicious user activity. 9. Educate administrators and users about the risk and encourage reporting of anomalies related to WordPress dashboard usage. These steps go beyond generic advice by focusing on plugin-specific controls, access restrictions, and proactive monitoring tailored to the vulnerability context.
