CVE-2025-68911 is a missing authorization vulnerability affecting the solacewp Solace WordPress plugin, specifically versions up to and including 2.1.16. The vulnerability arises from incorrectly configured access control security levels, which allow an attacker with low privileges to access sensitive data without proper authorization checks. The CVSS 3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity (I:N) or availability (A:N). This means an attacker who can authenticate with low-level credentials can remotely exploit the vulnerability to access confidential information that should be restricted. No known exploits are currently reported in the wild, and no official patches have been linked yet, indicating the need for proactive mitigation. The vulnerability's root cause is the absence or misconfiguration of authorization checks within the plugin's access control mechanisms, which is a common security weakness in web applications and plugins. Organizations using this plugin should be aware that attackers do not need to escalate privileges or trick users to exploit this flaw, increasing the risk of data leakage.

For European organizations, the primary impact is unauthorized disclosure of sensitive information managed or stored via the Solace plugin on WordPress sites. This could include customer data, internal documents, or configuration details, potentially leading to privacy violations under GDPR and reputational damage. Since the vulnerability does not affect integrity or availability, the risk of data tampering or service disruption is low. However, the confidentiality breach alone can have significant regulatory and compliance consequences, especially for sectors handling personal or sensitive data such as finance, healthcare, and government. The ease of exploitation over the network with low privileges increases the likelihood of targeted attacks or opportunistic scanning by threat actors. Organizations relying on WordPress plugins for critical functions should consider this vulnerability a serious concern, particularly if the plugin is used in environments with sensitive or regulated data. The absence of known exploits provides a window for remediation before active exploitation occurs.

1. Immediately audit all Solace plugin installations to identify versions up to 2.1.16 and assess their access control configurations. 2. Restrict low-privilege user roles from accessing sensitive plugin functions or data until patches are available. 3. Implement strict role-based access control (RBAC) policies within WordPress to minimize unnecessary permissions. 4. Monitor logs for unusual access patterns or attempts to access restricted data via the plugin. 5. Engage with solacewp vendor channels to obtain official patches or updates addressing this vulnerability as soon as they are released. 6. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 7. Educate administrators on the importance of plugin security and timely updates. 8. If feasible, isolate or sandbox WordPress instances running vulnerable plugins to limit potential data exposure.
