CVE-2025-26750 Overview
CVE-2025-26750 is a missing authorization vulnerability in the appsbd Vitepos (vitepos-lite) WordPress plugin. The flaw affects all versions up to and including 3.1.3. An authenticated attacker with low privileges can exploit incorrectly configured access control checks to reach functionality that should be restricted. The weakness is classified under CWE-862: Missing Authorization. Exploitation occurs over the network without user interaction, and the resulting impact centers on unauthorized read access to sensitive data.
Critical Impact
Authenticated users with minimal privileges can bypass access controls in Vitepos to access data intended for higher-privilege roles.
Affected Products
- appsbd Vitepos (vitepos-lite) WordPress plugin
- All versions from initial release through 3.1.3
- WordPress sites running the vulnerable plugin with multiple user roles

Technical Details for CVE-2025-26750
Vulnerability Analysis
The Vitepos plugin exposes point-of-sale functionality for WordPress-based storefronts. One or more plugin endpoints fail to enforce capability or role checks before processing requests. Any authenticated user, including low-privilege accounts such as subscribers or cashiers, can invoke these endpoints and retrieve confidential data. The confidentiality impact is high, while integrity and availability remain unaffected. This behavior matches the pattern described in the Patchstack Vulnerability Report.
Root Cause
The root cause is missing authorization logic in one or more plugin handlers. WordPress plugins typically enforce access using current_user_can() checks or nonce validation tied to a capability. Vitepos handlers omit these checks or rely on client-side controls that attackers bypass by calling the underlying endpoints directly. This design flaw falls under broken access control, where the application authenticates the user but never verifies whether the user is authorized for the requested action.
Attack Vector
An attacker requires only a valid low-privilege account on the target WordPress site. The attacker sends crafted HTTP requests to the vulnerable Vitepos AJAX or REST endpoints, invoking functions reserved for administrators or store managers. Because the plugin does not validate the caller's role, the server returns the requested data or performs the requested action. No user interaction is required, and the attack traverses the network directly to the WordPress admin-ajax or REST interface.
No public proof-of-concept code is available. See the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-26750
Indicators of Compromise
- Unexpected POST or GET requests to /wp-admin/admin-ajax.php referencing Vitepos actions from non-administrative user sessions
- REST API calls to Vitepos namespaces originating from accounts that should not access point-of-sale data
- Unusual data export activity or bulk record retrieval tied to low-privilege user IDs
- Access log entries showing repeated Vitepos endpoint invocation from a single authenticated session
Detection Strategies
- Review WordPress access logs for Vitepos plugin endpoints invoked by users below the Shop Manager or Administrator role
- Correlate authenticated session IDs with the plugin actions they trigger to surface role mismatches
- Deploy a web application firewall rule that inspects the action parameter of admin-ajax.php requests targeting Vitepos handlers
- Audit database read patterns for point-of-sale tables to identify queries originating from unauthorized user contexts
Monitoring Recommendations
- Enable verbose logging on the WordPress site and forward logs to a centralized analytics platform for role-based query analysis
- Alert on any authenticated user accessing Vitepos administrative actions outside the expected admin role
- Track plugin version inventory across all managed WordPress instances to identify sites running vitepos-lite 3.1.3 or earlier
How to Mitigate CVE-2025-26750
Immediate Actions Required
- Identify all WordPress sites running the Vitepos (vitepos-lite) plugin at version 3.1.3 or earlier
- Update the plugin to a patched release once the vendor publishes a fixed version
- Audit existing low-privilege user accounts for unusual activity referencing Vitepos endpoints
- Rotate credentials for any accounts suspected of exploiting the vulnerability
Patch Information
The Patchstack advisory tracks fix availability for versions later than 3.1.3. Administrators should monitor the plugin's WordPress.org listing and apply the vendor-issued update as soon as it is released. Confirm the installed version by inspecting the plugin header in wp-content/plugins/vitepos-lite/vitepos-lite.php after upgrade.
Workarounds
- Deactivate and remove the Vitepos plugin until a patched version is available if the point-of-sale functionality is not business-critical
- Restrict access to /wp-admin/admin-ajax.php and REST endpoints through a web application firewall that filters by authenticated role
- Limit new user registration and audit existing low-privilege accounts to reduce the pool of potential attackers
- Enforce IP allow-listing for the WordPress administrative interface where operationally feasible
# Example WordPress CLI command to identify vulnerable installations
wp plugin list --name=vitepos-lite --fields=name,status,version
# Deactivate the plugin as an interim measure
wp plugin deactivate vitepos-lite
