CVE-2025-30828: Timetics Auth Bypass Vulnerability

CVE-2025-30828 Overview

CVE-2025-30828 is a missing authorization vulnerability in the Arraytics Timetics plugin for WordPress. The flaw affects Timetics versions up to and including 1.0.29. It stems from incorrectly configured access control on plugin endpoints, allowing unauthenticated network attackers to reach functionality that should require authentication. The weakness is tracked under CWE-862: Missing Authorization. According to Patchstack, the issue enables broken access control against affected WordPress sites running the plugin.

Critical Impact
Unauthenticated attackers can reach protected Timetics functionality over the network, causing limited integrity impact on affected WordPress sites.

Affected Products

Technical Details for CVE-2025-30828

Vulnerability Analysis

The Timetics plugin exposes one or more endpoints without adequate authorization checks. An attacker sends network requests directly to these endpoints and bypasses the intended access control model. Because the check for the caller's role or capability is missing, the plugin processes the request as if it originated from an authorized user.

The attack requires no authentication, no user interaction, and can be executed remotely. Impact is limited to integrity, as the flaw exposes actions rather than sensitive data or availability disruption. Attackers can invoke plugin operations they should not have permission to trigger.

Root Cause

The root cause is an incorrectly configured access control security level on Timetics endpoints [CWE-862]. WordPress plugins must enforce capability checks using functions such as current_user_can() and validate nonces on state-changing REST or AJAX routes. In vulnerable Timetics builds up to 1.0.29, these authorization checks are either absent or improperly scoped for one or more handlers.

Attack Vector

Exploitation occurs over the network against the WordPress site hosting Timetics. An attacker crafts HTTP requests to the vulnerable plugin endpoint without providing valid credentials or elevated capabilities. The server processes the request and executes the underlying action, resulting in broken access control. No verified public exploit code or proof-of-concept has been published for CVE-2025-30828 at the time of writing. Refer to the Patchstack advisory for further technical detail.

Detection Methods for CVE-2025-30828

Indicators of Compromise

Unexpected requests to Timetics REST or AJAX endpoints under /wp-json/timetics/ or admin-ajax.php originating from unauthenticated sessions.
WordPress audit log entries showing plugin actions performed without an associated logged-in user.
Unauthorized creation, modification, or enumeration of Timetics bookings, appointments, or configuration records.

Detection Strategies

Inspect web server access logs for anomalous request patterns targeting Timetics plugin routes from external IP addresses.
Deploy a Web Application Firewall (WAF) rule that flags requests to Timetics endpoints missing valid authentication cookies or nonces.
Correlate WordPress activity logs with authentication events to identify plugin actions lacking a corresponding user session.

Monitoring Recommendations

Track the installed Timetics plugin version across all WordPress instances and alert on any host running 1.0.29 or earlier.
Monitor for spikes in traffic to /wp-json/timetics/ endpoints and baseline expected request volume.
Enable file integrity monitoring on the WordPress wp-content/plugins/timetics/ directory to detect tampering.

How to Mitigate CVE-2025-30828

Immediate Actions Required

Upgrade the Timetics plugin to a version later than 1.0.29 as soon as a fixed release is available from Arraytics.
Audit WordPress sites for the presence of Timetics and inventory versions to prioritize patching.
Review recent Timetics data for unauthorized changes and revert suspicious modifications.

Patch Information

Update Timetics to a release above 1.0.29 that includes proper capability and nonce checks on the affected endpoints. Consult the Patchstack advisory for the specific fixed version and vendor guidance.

Workarounds

Deactivate and remove the Timetics plugin until an updated version is installed if the plugin is not business-critical.
Restrict access to Timetics endpoints at the WAF or reverse proxy layer, allowing only authenticated administrative IP ranges.
Enforce virtual patching through a WordPress security plugin that provides broken access control mitigations for Timetics.

bash

# Example: block unauthenticated access to Timetics REST endpoints at the nginx layer
location ~ ^/wp-json/timetics/ {
    if ($http_cookie !~ "wordpress_logged_in_") {
        return 403;
    }
    try_files $uri $uri/ /index.php?$args;
}
