CVE-2025-50009 Overview
CVE-2025-50009 is a missing authorization vulnerability in the Climax Themes Kata Plus WordPress plugin. The flaw affects kata-plus versions up to and including 1.5.3. It stems from incorrectly configured access control security levels, allowing authenticated users with low privileges to invoke functionality that should be restricted [CWE-862].
The issue is tracked as a broken access control weakness and can be triggered over the network without user interaction. Successful exploitation impacts integrity and availability of affected WordPress installations that rely on the Kata Plus plugin.
Critical Impact
Authenticated attackers with minimal privileges can perform actions restricted to higher-privileged roles, enabling limited tampering and disruption of WordPress sites running Kata Plus <= 1.5.3.
Affected Products
- Climax Themes Kata Plus (kata-plus) plugin for WordPress
- All versions from initial release through 1.5.3
- WordPress sites with the Kata Plus plugin activated
Discovery Timeline
- 2025-06-20 - CVE-2025-50009 published to the National Vulnerability Database (NVD)

Technical Details for CVE-2025-50009
Vulnerability Analysis
The vulnerability is a missing authorization flaw classified under [CWE-862]. Kata Plus exposes one or more plugin actions that do not properly verify the caller's capability before executing sensitive operations. The plugin relies on incorrectly configured access control security levels, so privileged functionality is reachable by lower-privileged authenticated users.
The access vector is network-based, requires low attack complexity, and needs low-privilege authentication. There is no user interaction requirement. The impact is limited to integrity and availability, while confidentiality is not directly affected.
Broken access control in WordPress plugins commonly appears when plugin authors register AJAX handlers or REST routes without current_user_can() checks, or when nonces are validated without any accompanying capability verification. In Kata Plus, the plugin permits requests from users whose role should not grant access to the affected endpoints.
Root Cause
The root cause is an incorrect authorization decision inside plugin request handlers. The affected endpoints either omit capability checks entirely or evaluate them against a role level that is too permissive. As a result, the plugin trusts that any authenticated session is allowed to reach the protected functionality.
Attack Vector
An attacker with a valid low-privileged WordPress account, such as a Subscriber or Contributor on sites where registration is enabled, sends crafted HTTP requests to the vulnerable plugin endpoints. The plugin executes the requested action without enforcing the intended role restriction. See the Patchstack Vulnerability Report for endpoint-level detail.
No verified public exploit code is available at the time of publication. The vulnerability is described in prose only because no proof-of-concept has been released.
Detection Methods for CVE-2025-50009
Indicators of Compromise
- Unexpected POST or GET requests to /wp-admin/admin-ajax.php or REST endpoints containing kata-plus handlers from low-privileged user sessions.
- Modifications to plugin settings, options, or content that cannot be attributed to Administrator or Editor accounts.
- New or altered WordPress wp_options entries and post metadata created by non-privileged authenticated users.
Detection Strategies
- Audit WordPress access logs for authenticated requests to Kata Plus endpoints originating from accounts below the Editor role.
- Correlate WordPress user activity logs with plugin configuration changes to identify authorization anomalies.
- Compare the installed plugin version against 1.5.3 and flag any host still running an unpatched release.
Monitoring Recommendations
- Enable WordPress audit logging plugins to capture role-based action attempts and REST/AJAX invocations.
- Forward web server and application logs to a centralized SIEM or data lake for behavioral analysis of low-privileged accounts.
- Alert on spikes in admin-ajax.php traffic tied to the kata-plus action prefix.
How to Mitigate CVE-2025-50009
Immediate Actions Required
- Update the Kata Plus plugin to a version later than 1.5.3 as soon as the vendor publishes a fixed release.
- Restrict new user registration on public WordPress sites where the plugin is installed to reduce the pool of exploitable accounts.
- Review existing low-privileged accounts and remove any that are not required for business operations.
Patch Information
At the time of NVD publication, the affected range is documented as "from n/a through <= 1.5.3". Administrators should consult the Patchstack Vulnerability Report for the current fixed version and apply it through the standard WordPress plugin update workflow.
Workarounds
- Deactivate the Kata Plus plugin until a patched version is installed if the plugin is not business-critical.
- Deploy a Web Application Firewall (WAF) rule to block requests to Kata Plus AJAX and REST endpoints from users below the Editor role.
- Enforce least-privilege role assignments and disable open registration on affected WordPress sites.
# Configuration example: disable open registration and update plugin via WP-CLI
wp option update users_can_register 0
wp plugin update kata-plus
wp plugin list --name=kata-plus --fields=name,status,version
