CVE-2025-58816 is a security vulnerability classified under CWE-862 (Missing Authorization) found in the WordPress plugin 'Product Carousel Slider for Elementor' developed by Plugin Devs. This vulnerability arises due to improperly configured access control mechanisms within the plugin, allowing users with limited privileges to perform actions or access resources that should be restricted. The affected versions include all versions up to 2.1.3, though the exact range is unspecified ('n/a' listed). The vulnerability does not impact confidentiality or integrity but affects availability, as indicated by the CVSS vector (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L). This means the attack can be executed remotely over the network, requires low attack complexity, requires the attacker to have some privileges (PR:L), and requires user interaction (UI:R). The scope remains unchanged (S:U), and the impact is limited to availability (A:L) with no impact on confidentiality or integrity. The CVSS score is 3.5, categorized as low severity. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability could allow an authenticated user with limited privileges to disrupt the availability of certain plugin functionalities, potentially causing denial of service or degraded user experience on websites using this plugin. Since the plugin is integrated with Elementor, a popular WordPress page builder, the vulnerability could affect e-commerce or product showcase sites relying on the carousel slider for displaying products.

For European organizations, especially those operating e-commerce platforms or marketing websites built on WordPress using Elementor and the Product Carousel Slider plugin, this vulnerability could lead to service disruption or degraded user experience. Although the impact on confidentiality and integrity is nil, availability issues can affect business operations, customer trust, and revenue. Organizations with limited administrative controls or insufficient monitoring could see exploitation attempts by authenticated users (e.g., low-privileged employees or compromised accounts). The low CVSS score suggests limited risk, but availability disruptions on customer-facing sites can have outsized reputational and financial consequences. Additionally, the requirement for user interaction and some privileges reduces the likelihood of widespread exploitation but does not eliminate risk in environments with many users or weak privilege management. European organizations with strict uptime requirements or regulatory obligations for service availability should consider this vulnerability significant enough to address promptly.

1. Implement strict role-based access control (RBAC) policies to minimize the number of users with privileges that could exploit this vulnerability. 2. Monitor user activities and audit logs for unusual actions related to the Product Carousel Slider plugin, focusing on users with low privileges performing unexpected operations. 3. Temporarily disable or restrict access to the Product Carousel Slider plugin functionalities until a patch or update is available. 4. Regularly check for updates or security advisories from Plugin Devs and Elementor regarding patches addressing this vulnerability. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the carousel slider endpoints. 6. Educate users about phishing and social engineering risks to reduce the chance of attackers gaining authenticated access. 7. Conduct internal penetration testing focusing on plugin access controls to identify and remediate similar authorization issues proactively.
