CVE-2025-58613 Overview
CVE-2025-58613 is a missing authorization vulnerability in the Barn2 Plugins Posts Table with Search & Sort WordPress plugin. The flaw affects all versions up to and including 1.4.10. Attackers can exploit incorrectly configured access control security levels to access functionality that should be restricted. The vulnerability is categorized as broken access control [CWE-862] and is remotely exploitable over the network without authentication or user interaction. Successful exploitation results in unauthorized disclosure of low-sensitivity data from affected WordPress sites.
Critical Impact
Unauthenticated network attackers can bypass access controls in the Posts Table with Search & Sort plugin to reach protected functionality, resulting in unauthorized data exposure.
Affected Products
- Barn2 Plugins Posts Table with Search & Sort (posts-data-table)
- Versions from n/a through 1.4.10
- WordPress sites running the affected plugin

Technical Details for CVE-2025-58613
Vulnerability Analysis
The vulnerability stems from missing authorization checks within the Posts Table with Search & Sort plugin. The plugin exposes functionality without properly validating whether the requesting user holds the required capability or role. This class of flaw, tracked as [CWE-862] Missing Authorization, occurs when code paths reachable via HTTP requests skip capability verification before performing an action or returning data.
Because the flaw resides in a WordPress plugin that renders posts in searchable and sortable tables, the affected endpoints likely process AJAX or REST requests. When these handlers fail to invoke functions such as current_user_can() or verify nonces, any network client can invoke them. The advisory classifies the impact as confidentiality loss only, indicating attackers can read data they should not access but cannot directly modify posts or take the site offline through this flaw.
Root Cause
The root cause is an incorrectly configured access control security level in one or more of the plugin's request handlers. The plugin does not verify user privileges before executing the affected functionality, allowing anonymous requests to reach code intended for authorized users.
Attack Vector
An unauthenticated remote attacker sends a crafted HTTP request to the vulnerable plugin endpoint on a WordPress site. Because the request requires no privileges and no user interaction, the attack can be scripted at scale against WordPress installations exposing the plugin. Refer to the Patchstack Vulnerability Report for endpoint-level technical details.
Detection Methods for CVE-2025-58613
Indicators of Compromise
- Anomalous unauthenticated requests to WordPress AJAX endpoints (/wp-admin/admin-ajax.php) referencing posts-data-table actions.
- REST API calls under /wp-json/ targeting Posts Table with Search & Sort routes from unauthenticated sessions.
- Elevated volumes of GET or POST requests from a single source enumerating post data through the plugin.
Detection Strategies
- Inventory WordPress sites and confirm whether the posts-data-table plugin is installed at version 1.4.10 or earlier.
- Review web server access logs for requests to plugin-specific query parameters or AJAX actions originating from unauthenticated clients.
- Deploy WAF rules that flag access to plugin endpoints without a valid WordPress authentication cookie.
Monitoring Recommendations
- Alert on spikes in requests to admin-ajax.php associated with the plugin's action names.
- Correlate outbound data volume from WordPress hosts against baselines to catch bulk scraping.
- Monitor plugin version drift across managed WordPress fleets to identify unpatched instances.
How to Mitigate CVE-2025-58613
Immediate Actions Required
- Update Posts Table with Search & Sort to a version above 1.4.10 as soon as the vendor releases a fixed release.
- Audit user roles and capabilities on affected WordPress sites to confirm no unauthorized changes occurred.
- Restrict administrative endpoints behind IP allow-lists or authentication proxies where feasible.
Patch Information
At the time of publication, the advisory lists affected versions from n/a through 1.4.10. Consult the Patchstack Vulnerability Report and the Barn2 Plugins vendor site for the latest fixed release information.
Workarounds
- Disable and remove the Posts Table with Search & Sort plugin until a patched version is available.
- Deploy a WordPress-aware web application firewall to block unauthenticated requests to plugin endpoints.
- Apply virtual patching via the Patchstack service or an equivalent mitigation platform to shield vulnerable endpoints.
