CVE-2025-58613 is a Missing Authorization vulnerability (CWE-862) found in the Barn2 Plugins product 'Posts Table with Search & Sort'. This plugin is used to enhance WordPress sites by providing advanced table views with search and sort capabilities for posts. The vulnerability arises due to incorrectly configured access control mechanisms, allowing unauthorized users to access certain functionalities or data that should be restricted. Specifically, the plugin fails to properly verify whether a user has the necessary permissions before granting access to certain post table data or features. The affected versions include all versions up to 1.4.10, with no specific version exclusions noted. The CVSS v3.1 base score is 5.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), unchanged scope (S:U), and limited confidentiality impact (C:L), with no impact on integrity or availability. This means an attacker can remotely exploit the vulnerability without authentication or user interaction to gain limited access to data that should be protected. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because it undermines the access control model of the plugin, potentially exposing sensitive post data or administrative features to unauthorized users. Since the plugin is used on WordPress sites, the risk is tied to the prevalence of the plugin and the sensitivity of the data managed through it. The lack of authentication requirement and low attack complexity make this vulnerability relatively easy to exploit remotely, increasing its risk profile despite the medium severity rating.

For European organizations, the impact of this vulnerability depends on the extent to which they use the Barn2 Plugins 'Posts Table with Search & Sort' plugin on their WordPress sites. Organizations that rely on WordPress for content management and use this plugin to display or manage sensitive or proprietary post data could face unauthorized data exposure. This could lead to leakage of confidential information, intellectual property, or internal communications. Although the vulnerability does not affect data integrity or availability, unauthorized read access can still cause reputational damage, regulatory compliance issues (especially under GDPR if personal data is exposed), and potential competitive disadvantage. Public sector entities, educational institutions, and businesses with customer-facing WordPress sites in Europe may be particularly concerned if sensitive data is displayed or managed via this plugin. The ease of exploitation without authentication increases the risk of automated scanning and exploitation attempts by attackers. However, the absence of known exploits in the wild suggests that immediate widespread impact may be limited, but proactive mitigation is advised to prevent future exploitation.

European organizations should immediately audit their WordPress installations to identify the presence of the Barn2 Plugins 'Posts Table with Search & Sort' plugin. If found, they should verify the plugin version and upgrade to a patched version once available from the vendor. In the interim, organizations can mitigate risk by restricting access to the affected plugin's functionality through web application firewalls (WAFs) or by limiting access to the WordPress admin and relevant endpoints via IP whitelisting or VPNs. Additionally, review and tighten WordPress user roles and permissions to ensure minimal necessary access is granted. Monitoring web server logs for unusual access patterns targeting the plugin's endpoints can help detect exploitation attempts. Organizations should also consider disabling or removing the plugin if it is not essential. Regular backups and incident response plans should be updated to include scenarios involving unauthorized data access via plugins. Finally, maintain awareness of vendor communications for patch releases and apply updates promptly.
