CVE-2026-57392 Overview
CVE-2026-57392 is a Missing Authorization vulnerability [CWE-862] affecting the Themefic Tourfic plugin for WordPress. The flaw stems from incorrectly configured access control security levels within the plugin. Attackers can exploit exposed functionality without proper authorization checks, leading to unauthorized actions against affected sites. The issue affects all Tourfic plugin versions from n/a through <= 2.22.5. The vulnerability is exploitable over the network without authentication or user interaction.
Critical Impact
Unauthenticated network attackers can invoke restricted plugin functionality due to missing authorization checks, resulting in limited integrity and availability impact on affected WordPress sites.
Affected Products
- Themefic Tourfic WordPress plugin
- Tourfic versions through 2.22.5
- WordPress sites running vulnerable Tourfic plugin builds

Technical Details for CVE-2026-57392
Vulnerability Analysis
The Tourfic plugin exposes functionality without enforcing proper authorization checks on incoming requests. Missing Authorization [CWE-862] occurs when an application fails to verify that a requesting actor possesses the required permissions before granting access to a resource or action. In this case, endpoints intended for privileged users lack capability checks or nonce verification. Attackers can send crafted requests directly to vulnerable handlers and trigger actions that should require elevated privileges.
The EPSS score is 0.242% with a percentile of 15.399, indicating a low current probability of exploitation activity. However, plugins with broken access control in the WordPress ecosystem are routinely targeted by automated scanners.
Root Cause
The root cause is incorrectly configured access control security levels within Tourfic plugin handlers. The plugin does not consistently validate the caller's WordPress capabilities or verify request authenticity before executing sensitive operations. This design flaw allows unauthenticated actors to reach code paths that were intended for authenticated or administrative users.
Attack Vector
Exploitation occurs over the network against a WordPress site running a vulnerable Tourfic version. An attacker sends HTTP requests to plugin-exposed endpoints, such as AJAX actions or REST routes, without supplying valid authentication or capability context. Because the plugin skips authorization enforcement, the request executes and produces limited integrity and availability impact on affected data or plugin behavior.
No public proof-of-concept code is available. Technical specifics are documented in the Patchstack Vulnerability Report.
Detection Methods for CVE-2026-57392
Indicators of Compromise
- Unexpected modifications to Tourfic-managed content such as tours, hotels, or bookings without corresponding admin activity in WordPress audit logs.
- HTTP requests to Tourfic AJAX handlers or REST endpoints originating from unauthenticated sessions or unusual IP addresses.
- New or altered plugin data records appearing outside normal administrator working hours.
Detection Strategies
- Review WordPress access logs for POST requests to admin-ajax.php referencing Tourfic actions from unauthenticated clients.
- Enable WordPress activity logging plugins to correlate plugin state changes with authenticated user sessions.
- Deploy a Web Application Firewall rule set that flags anonymous requests to Tourfic-specific endpoints.
Monitoring Recommendations
- Monitor the Tourfic plugin version across all managed WordPress instances and alert on installations at or below 2.22.5.
- Track the volume of requests to plugin AJAX and REST routes to detect scanning behavior.
- Alert on outbound anomalies from the web host that could indicate post-exploitation activity following unauthorized action execution.
How to Mitigate CVE-2026-57392
Immediate Actions Required
- Identify all WordPress instances with the Tourfic plugin installed and inventory their versions.
- Upgrade Tourfic to a version later than 2.22.5 as soon as the vendor releases a fixed build.
- Restrict access to WordPress admin and AJAX endpoints from untrusted networks where feasible.
Patch Information
Refer to the Patchstack Vulnerability Report for the current patch status and vendor guidance. Apply the fixed Tourfic release published by Themefic once available and verify the update in the WordPress plugin dashboard.
Workarounds
- Temporarily disable the Tourfic plugin on production sites until a patched release is installed.
- Deploy WAF rules that block unauthenticated requests to Tourfic AJAX and REST endpoints.
- Enforce IP allowlisting on wp-admin and admin-ajax.php for administrator networks to reduce the exposed attack surface.
