CVE-2026-56069: Toolset Forms IDOR Auth Bypass Vulnerability

CVE-2026-56069 Overview

CVE-2026-56069 is an Insecure Direct Object References (IDOR) vulnerability affecting the Toolset Forms WordPress plugin (also known as cred-frontend-editor) in versions up to and including 2.6.24. The flaw allows unauthenticated attackers to manipulate object identifiers over the network and interact with resources they should not access. The weakness is tracked under CWE-639: Authorization Bypass Through User-Controlled Key. Successful exploitation impacts availability of the affected WordPress site. No authentication or user interaction is required to trigger the issue.

Critical Impact
Unauthenticated network attackers can abuse direct object references in Toolset Forms to disrupt availability of WordPress sites running vulnerable versions of the plugin.

Affected Products

Toolset Forms (cred-frontend-editor) WordPress plugin versions <= 2.6.24
WordPress sites using Toolset Forms for frontend content submission and editing
Any WordPress deployment bundling the vulnerable plugin release

Technical Details for CVE-2026-56069

Vulnerability Analysis

The vulnerability is an Insecure Direct Object Reference (IDOR) in the Toolset Forms plugin. The plugin exposes endpoints that accept object identifiers supplied by the client without verifying that the requesting user has authorization to act on the referenced object. Because no authentication is required, an attacker can send crafted requests over the network and reference arbitrary internal objects.

The vector is remote, attack complexity is low, and no privileges or user interaction are required. Impact is scoped to availability, meaning an attacker can disrupt service or corrupt state for objects that should be inaccessible. Confidentiality and integrity are not directly impacted according to the published CVSS vector.

The Exploit Prediction Scoring System places this issue in the lower percentile range, and no public proof-of-concept or in-the-wild exploitation has been confirmed at publication time.

Root Cause

The root cause is missing authorization enforcement on request parameters that reference internal objects [CWE-639]. Toolset Forms trusts user-supplied identifiers such as post IDs, form IDs, or record keys and performs actions against them without validating ownership or capability. This design flaw lets an unauthenticated caller substitute another object's identifier to invoke privileged operations.

Attack Vector

An attacker crafts HTTP requests to Toolset Forms endpoints and supplies object identifiers of resources belonging to other users or system components. Because the plugin performs no authorization check tying the caller to the referenced object, the plugin processes the request. Repeated or targeted requests can be used to affect availability of records or plugin functionality.

No verified public exploit code is available. See the Patchstack Vulnerability Report for advisory details.

Detection Methods for CVE-2026-56069

Indicators of Compromise

Unauthenticated POST or GET requests to Toolset Forms endpoints such as those under /wp-admin/admin-ajax.php referencing cred_* actions with varying form_id or post_id parameters.
Anomalous sequences of requests iterating through numeric object identifiers from a single source IP.
Unexpected modifications, deletions, or errors on WordPress posts or custom content types tied to Toolset Forms.

Detection Strategies

Review WordPress and web server access logs for unauthenticated traffic to cred-frontend-editor handlers with client-supplied IDs.
Enable WordPress plugin audit logging to correlate object-level changes with the originating session or IP address.
Alert on high request volumes hitting Toolset Forms AJAX actions without an authenticated session cookie.

Monitoring Recommendations

Forward WordPress, PHP, and web server logs to a centralized SIEM for correlation across sites.
Monitor for spikes in HTTP 200 responses to Toolset Forms endpoints from unauthenticated sources.
Track plugin version inventory across all WordPress instances to identify hosts still running <= 2.6.24.

How to Mitigate CVE-2026-56069

Immediate Actions Required

Identify all WordPress instances running Toolset Forms <= 2.6.24 and prioritize upgrade.
Upgrade Toolset Forms to a fixed release above 2.6.24 as published by the vendor.
Restrict access to WordPress administrative and AJAX endpoints using a web application firewall while patching is in progress.

Patch Information

Refer to the Patchstack advisory for Toolset Forms for the fixed version and vendor guidance. Apply the upgrade through the WordPress plugin manager or via WP-CLI, then verify the reported version is above 2.6.24.

Workarounds

Deactivate the Toolset Forms plugin until an upgrade can be applied if the frontend forms functionality is not business-critical.
Deploy WAF rules that block unauthenticated requests to cred_* AJAX actions and reject requests supplying object IDs from anonymous sources.
Limit exposure of /wp-admin/admin-ajax.php to authenticated sessions where feasible through reverse proxy or plugin-level controls.

bash

# Configuration example: verify and upgrade the Toolset Forms plugin via WP-CLI
wp plugin get cred-frontend-editor --field=version
wp plugin update cred-frontend-editor
wp plugin get cred-frontend-editor --field=version
