CVE-2025-31863: Agency Toolkit Auth Bypass Vulnerability

CVE-2025-31863 Overview

CVE-2025-31863 is a Missing Authorization vulnerability [CWE-862] in the inspry Agency Toolkit WordPress plugin. The flaw affects all versions up to and including 1.0.24. An unauthenticated attacker can reach plugin functionality that should be restricted to privileged users due to incorrectly configured access control checks.

The issue is exploitable over the network without user interaction or prior authentication. Successful exploitation results in limited disclosure of information from vulnerable WordPress sites running the plugin.

Critical Impact
Unauthenticated network-accessible broken access control in a WordPress plugin exposes restricted plugin functionality to remote attackers, enabling unauthorized read access on affected sites.

Affected Products

inspry Agency Toolkit (agency-toolkit) WordPress plugin
Versions from initial release through <= 1.0.24
WordPress installations with the plugin activated

Technical Details for CVE-2025-31863

Vulnerability Analysis

The vulnerability is a Missing Authorization weakness classified as [CWE-862]. The Agency Toolkit plugin exposes one or more actions or endpoints without verifying the caller's capability or role. WordPress plugins typically enforce authorization through current_user_can() checks or capability-based nonces. When these checks are absent or misconfigured, restricted functionality becomes reachable by unauthenticated users.

Based on the Patchstack advisory, the flaw is categorized as broken access control affecting plugin endpoints. The impact is limited to confidentiality, with no direct integrity or availability effect reported. This suggests the exposed functionality returns data or state information rather than allowing writes.

Sites running any version through 1.0.24 are affected. Administrators should treat any endpoint added by the plugin as potentially reachable by anonymous requests until patched.

Root Cause

The root cause is a missing or incorrectly configured access control check on plugin functionality. The plugin registers actions accessible via WordPress request handlers (such as admin-ajax.php or REST routes) without validating that the requester holds the required capability. Access control levels are enforced inconsistently, so restricted operations execute for unauthenticated callers.

Attack Vector

Exploitation requires only network access to the target WordPress site. The attacker sends a crafted HTTP request to the plugin endpoint that lacks the authorization check. No credentials, session, or user interaction is needed. The server processes the request as if it came from an authorized user and returns the protected data.

Refer to the Patchstack Vulnerability Report for endpoint-specific technical details.

Detection Methods for CVE-2025-31863

Indicators of Compromise

Unauthenticated HTTP requests to Agency Toolkit plugin endpoints under /wp-admin/admin-ajax.php or /wp-json/ paths
Anomalous request volume from single source IPs targeting agency-toolkit actions
Access log entries referencing plugin actions without an accompanying authenticated session cookie

Detection Strategies

Inventory WordPress installations and identify sites running Agency Toolkit at version <= 1.0.24
Review web server access logs for requests to plugin endpoints from unauthenticated sources
Deploy web application firewall rules to flag requests matching known plugin action names without valid nonces

Monitoring Recommendations

Ingest WordPress and web server logs into a centralized log platform for correlation and long-term retention
Alert on spikes in admin-ajax.php traffic where the action parameter references Agency Toolkit handlers
Monitor for outbound data volumes from WordPress hosts that could indicate scraping of exposed plugin data

How to Mitigate CVE-2025-31863

Immediate Actions Required

Update the Agency Toolkit plugin to a version later than 1.0.24 as soon as a patched release is available from the vendor
Deactivate the plugin on affected sites until a patched version is installed if the functionality is not business critical
Restrict access to /wp-admin/ and plugin AJAX or REST endpoints at the network or WAF layer where feasible

Patch Information

Consult the Patchstack Vulnerability Report for vendor patch status. Site owners should apply the fixed release published by inspry through the WordPress plugin repository once available and confirm the installed version reports higher than 1.0.24.

Workarounds

Apply virtual patching rules through a WordPress-aware WAF to block unauthenticated requests to the vulnerable plugin actions
Enforce IP allowlisting on /wp-admin/ for administrative operations to reduce exposure of plugin endpoints
Remove the plugin entirely if it is not in active use and audit exported data for indicators of prior unauthorized access

bash

# Identify WordPress sites running the affected plugin version
wp plugin get agency-toolkit --field=version

# Deactivate the plugin until a patched release is applied
wp plugin deactivate agency-toolkit
