CVE-2025-3952 is a high-severity vulnerability affecting the Projectopia – WordPress Project Management plugin, versions up to and including 5.1.16. The root cause is a missing authorization check (CWE-862) in the 'pto_remove_logo' function, which allows authenticated users with Subscriber-level privileges or higher to delete arbitrary option values within the WordPress site. This capability bypass means that even low-privileged users can invoke this function without proper permission verification. By deleting critical option values, an attacker can cause the site to generate errors leading to denial of service (DoS) conditions, disrupting legitimate users’ access. The vulnerability is remotely exploitable over the network (AV:N), requires low attack complexity (AC:L), and only requires privileges equivalent to a Subscriber role (PR:L). No user interaction is needed (UI:N), and the scope remains unchanged (S:U). The impact is high on integrity and availability, as attackers can modify site configuration data and cause service outages, though confidentiality is not affected. No known exploits are currently reported in the wild, but the vulnerability’s characteristics make it a significant risk for WordPress sites using this plugin. The lack of a patch link suggests that a fix may not yet be available or publicly disclosed. Organizations using Projectopia should consider this vulnerability critical to address promptly to prevent potential service disruptions and unauthorized data modifications.

For European organizations relying on the Projectopia plugin for WordPress project management, this vulnerability poses a significant risk to service availability and data integrity. An attacker with minimal privileges (Subscriber-level) can disrupt business operations by causing denial of service through deletion of critical configuration options. This can lead to downtime, loss of productivity, and potential reputational damage. Since WordPress is widely used across various sectors including government, education, and private enterprises in Europe, the impact could extend to critical infrastructure and sensitive project management data. The vulnerability does not directly expose confidential data but undermines trust in the availability and reliability of affected web services. Organizations with multi-user WordPress environments where users have Subscriber or higher roles are particularly vulnerable. The ease of exploitation and the potential for widespread disruption make this a pressing concern for European entities that depend on Projectopia for managing projects and workflows.

1. Immediate mitigation should include restricting Subscriber-level user capabilities to prevent exploitation until a patch is available. This can be done by customizing user roles and capabilities using WordPress role management plugins to remove access to functions related to 'pto_remove_logo'. 2. Monitor and audit user activities, especially those with Subscriber or higher roles, to detect any unauthorized attempts to modify site options. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the vulnerable function or related endpoints. 4. Regularly back up WordPress site configurations and databases to enable quick restoration in case of data deletion or corruption. 5. Stay informed about updates from the Projectopia vendor and apply patches immediately once released. 6. Consider isolating or limiting plugin usage on critical systems or migrating to alternative project management solutions if immediate patching is not feasible. 7. Employ principle of least privilege for user roles, ensuring users only have the minimum necessary permissions to perform their tasks.
