CVE-2025-68575: Wappointment Auth Bypass Vulnerability

CVE-2025-68575 Overview

CVE-2025-68575 is a missing authorization vulnerability affecting the Wappointment WordPress plugin through version 2.7.6. The flaw stems from incorrectly configured access control security levels, allowing unauthenticated network attackers to access functionality that should require authorization. The issue is tracked under CWE-862: Missing Authorization and was published to the National Vulnerability Database on December 24, 2025.

Critical Impact
Unauthenticated attackers can interact with plugin functionality that lacks proper authorization checks, leading to limited integrity impact on affected WordPress sites running Wappointment.

Affected Products

Wappointment WordPress plugin versions through 2.7.6
WordPress sites with the vulnerable plugin installed and active
Appointment booking environments relying on Wappointment for scheduling

Technical Details for CVE-2025-68575

Vulnerability Analysis

The Wappointment plugin exposes one or more functions or endpoints that fail to perform adequate authorization checks before executing privileged operations. Under CWE-862, the software does not verify that the requesting user has permission to access the resource or perform the action. Attackers can send crafted HTTP requests to the affected endpoints without authentication. The vulnerability impacts integrity at a limited level, while confidentiality and availability remain unaffected per the published CVSS vector.

Root Cause

The root cause is broken access control within the plugin's request handlers. The plugin code paths do not validate user capabilities or nonce tokens before executing certain operations. WordPress plugins are expected to enforce authorization through functions such as current_user_can() and verify request authenticity through check_admin_referer() or wp_verify_nonce(). The absence of these checks in vulnerable handlers allows any caller to reach restricted logic.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker sends HTTP requests directly to the vulnerable plugin endpoint on a target WordPress site. Because no privileges are required, mass scanning and automated exploitation against exposed WordPress installations is feasible. The EPSS score is 0.032% as of June 2026, indicating low observed exploitation probability at this time.

No public proof-of-concept code has been verified. Refer to the Patchstack Vulnerability Database Entry for additional technical context.

Detection Methods for CVE-2025-68575

Indicators of Compromise

Unauthenticated POST or GET requests to Wappointment plugin endpoints under /wp-admin/admin-ajax.php or REST routes such as /wp-json/wappointment/
Unexpected modifications to appointment data, settings, or plugin configuration without corresponding administrator login events
Anomalous spikes in traffic targeting wp-content/plugins/wappointment/ paths

Detection Strategies

Inventory all WordPress installations and identify sites running Wappointment at version 2.7.6 or earlier
Inspect web server access logs for requests to Wappointment AJAX or REST endpoints originating from unauthenticated sessions
Correlate plugin configuration changes with authenticated administrator activity to identify discrepancies

Monitoring Recommendations

Enable WordPress audit logging to capture plugin setting changes and appointment record modifications
Forward web server and WordPress application logs to a centralized SIEM for retention and correlation
Configure alerting on bursts of requests to plugin endpoints from single source IP addresses

How to Mitigate CVE-2025-68575

Immediate Actions Required

Identify all WordPress sites running Wappointment version 2.7.6 or earlier and prioritize them for patching
Update the Wappointment plugin to a fixed version once released by the vendor
If a patch is not immediately deployable, disable the Wappointment plugin until remediation is available

Patch Information

Review the Patchstack Vulnerability Database Entry for the most current fixed-version guidance from the Wappointment team. Apply the vendor-supplied update through the standard WordPress plugin update mechanism and verify the installed version after upgrade.

Workarounds

Restrict access to WordPress administrative and plugin endpoints using web application firewall (WAF) rules
Block unauthenticated requests to Wappointment AJAX actions and REST routes at the reverse proxy or WAF layer
Limit network exposure of WordPress administrative paths to trusted IP ranges where feasible

bash

# Example nginx rule to block unauthenticated access to Wappointment REST routes
location ~* /wp-json/wappointment/ {
    if ($http_cookie !~* "wordpress_logged_in_") {
        return 403;
    }
}
