CVE-2026-61983 Overview
CVE-2026-61983 is a missing authorization vulnerability [CWE-862] in the Church Admin WordPress plugin developed by andy_moyle. The flaw stems from incorrectly configured access control security levels within the plugin. Unauthenticated attackers can reach functionality that should be restricted to authorized users. The vulnerability affects Church Admin versions up to and including 5.0.30.
The issue allows attackers to exploit protected endpoints over the network without any prior authentication or user interaction. Successful exploitation results in limited integrity impact on the affected WordPress site. Site administrators running the Church Admin plugin should treat this as a priority remediation item.
Critical Impact
Unauthenticated network attackers can exploit incorrectly configured access controls in Church Admin to perform actions that should require authorization, resulting in integrity impact on affected WordPress installations.
Affected Products
- WordPress Church Admin plugin by andy_moyle
- All versions from initial release through 5.0.30

Technical Details for CVE-2026-61983
Vulnerability Analysis
CVE-2026-61983 is classified as a missing authorization vulnerability [CWE-862]. The Church Admin plugin exposes functionality without properly validating whether the requesting user has permission to invoke it. This class of flaw is common in WordPress plugins that rely on nonce checks or client-side restrictions without enforcing capability checks server-side.
An attacker can craft requests directly against vulnerable plugin endpoints. Because the plugin does not verify user roles or capabilities before executing the requested action, the request completes successfully. The exploitable surface is limited to integrity impact and does not expose confidential data or affect availability.
The vulnerability is reachable remotely over the network. Exploitation requires no authentication and no user interaction. Public patch information is available through the Patchstack Vulnerability Report.
Root Cause
The root cause is the absence of proper authorization checks on one or more plugin actions. WordPress plugins should call current_user_can() with an appropriate capability before executing privileged operations. In this case, that verification is either missing or incorrectly configured, permitting unauthorized callers to trigger restricted functionality.
Attack Vector
The attack vector is network-based and can be executed by an unauthenticated remote user. An attacker sends a crafted HTTP request to a vulnerable plugin endpoint on a WordPress site running Church Admin 5.0.30 or earlier. The plugin processes the request without validating the caller's authorization, causing the restricted action to execute.
No exploit code is publicly available at time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS score indicates low near-term exploitation probability.
Detection Methods for CVE-2026-61983
Indicators of Compromise
- Unexpected changes to Church Admin plugin data or configuration performed by unauthenticated sessions
- HTTP requests to Church Admin plugin endpoints originating from IP addresses without associated authenticated WordPress sessions
- WordPress activity logs showing plugin actions with no corresponding user login events
Detection Strategies
- Review WordPress access logs for requests targeting Church Admin plugin routes and AJAX actions from unauthenticated clients
- Deploy a web application firewall (WAF) rule to flag requests to plugin endpoints that lack valid authentication cookies
- Enable a WordPress audit logging plugin to track actions performed against Church Admin resources
Monitoring Recommendations
- Monitor the wp-admin/admin-ajax.php endpoint for calls referencing Church Admin actions from anonymous sessions
- Track modifications to database tables owned by the Church Admin plugin for unexpected write patterns
- Alert on outbound webhook or notification activity generated by the plugin outside normal administrative hours
How to Mitigate CVE-2026-61983
Immediate Actions Required
- Identify all WordPress instances running the Church Admin plugin and confirm installed versions
- Update Church Admin to a version later than 5.0.30 once the vendor releases a fixed release
- Restrict administrative access to WordPress management interfaces using IP allowlists where feasible
- Deploy a WAF rule blocking unauthenticated requests to Church Admin plugin endpoints until patching is complete
Patch Information
The vulnerability affects Church Admin versions up to and including 5.0.30. Refer to the Patchstack Vulnerability Report for updated fix availability and vendor guidance. Administrators should subscribe to WordPress plugin update notifications for the Church Admin plugin.
Workarounds
- Deactivate the Church Admin plugin until a patched version is installed if the plugin is not business-critical
- Apply WAF rules that require authenticated session cookies for requests to Church Admin plugin URLs
- Limit access to the WordPress site to trusted networks using server-level access controls such as .htaccess or reverse proxy rules
