CVE-2026-57395: Tourfic Authorization Bypass Vulnerability

CVE-2026-57395 Overview

CVE-2026-57395 is a Missing Authorization vulnerability [CWE-862] in the Themefic Tourfic plugin for WordPress. The flaw stems from incorrectly configured access control security levels, allowing authenticated users with low privileges to access functionality intended for higher-privileged roles. The issue affects Tourfic versions up to and including 2.22.5. Attackers exploit the vulnerability over the network with low complexity and no user interaction, requiring only low-level authenticated access. Successful exploitation compromises confidentiality by exposing data that should be restricted to authorized users.

Critical Impact
Authenticated attackers with low privileges can bypass access control checks in the Tourfic plugin and access restricted functionality or data on affected WordPress installations.

Affected Products

Themefic Tourfic plugin for WordPress, versions up to and including 2.22.5

Technical Details for CVE-2026-57395

Vulnerability Analysis

The Tourfic plugin implements booking and tour management features for WordPress sites. The vulnerability results from missing authorization checks on plugin endpoints or actions. An attacker holding a low-privilege authenticated account, such as a subscriber or customer, can invoke functionality that should be gated by role or capability checks. The attack vector is network-based and requires no user interaction, making exploitation straightforward once an attacker holds any valid account on the target site. The impact is limited to confidentiality, with no direct integrity or availability effect according to the published CVSS vector.

Root Cause

The root cause is an authorization gap classified as [CWE-862] Missing Authorization. The plugin does not consistently verify that the requesting user holds the capability required to execute the targeted action. Access control decisions appear to rely on incorrectly configured security levels rather than explicit capability checks such as WordPress current_user_can() verification against the intended role.

Attack Vector

An authenticated attacker sends crafted requests to plugin-exposed endpoints, AJAX handlers, or REST routes that lack proper capability checks. Because the server-side logic does not enforce the intended authorization boundary, the request executes and returns data or performs operations the user should not access. See the Patchstack Security Advisory for endpoint-level technical details.

Detection Methods for CVE-2026-57395

Indicators of Compromise

Unexpected requests from low-privilege accounts to Tourfic AJAX endpoints such as admin-ajax.php with action parameters tied to the plugin.
Access log entries showing subscriber or customer accounts retrieving booking, tour, or configuration data outside their normal scope.
WordPress audit logs recording data reads or state changes not correlated with administrator activity.

Detection Strategies

Review WordPress and web server access logs for requests to Tourfic plugin endpoints originating from non-administrative user sessions.
Correlate authenticated user role with the sensitivity of the accessed action to identify authorization mismatches.
Deploy WordPress security plugins or a WAF rule set that flags anomalous access patterns to plugin-provided routes.

Monitoring Recommendations

Enable verbose logging for admin-ajax.php and REST API requests targeting the tourfic namespace.
Alert on repeated requests from a single low-privilege session to plugin endpoints associated with tour management or bookings.
Track newly created low-privilege accounts followed by immediate plugin endpoint access.

How to Mitigate CVE-2026-57395

Immediate Actions Required

Identify all WordPress sites running the Tourfic plugin and confirm the installed version.
Update Tourfic to a version later than 2.22.5 once the vendor releases a fixed release.
Audit existing low-privilege user accounts and remove any that are unnecessary or suspicious.

Patch Information

Refer to the Patchstack Security Advisory for the vendor-supplied fixed version and patch guidance. All versions up to and including 2.22.5 are affected.

Workarounds

Restrict user registration on affected WordPress sites to trusted parties until the plugin is updated.
Apply web application firewall rules blocking requests from low-privilege sessions to sensitive Tourfic endpoints.
Temporarily disable the Tourfic plugin if patching is not feasible and the exposed functionality is not business-critical.

bash

# Configuration example: list and update the Tourfic plugin using WP-CLI
wp plugin list --name=tourfic --fields=name,status,version
wp plugin update tourfic
