CVE-2025-13093 in Devs CRM Plugin
Summary
by MITRE • 12/13/2025
The Devs CRM – Manage tasks, attendance and teams all together plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the '/wp-json/devs-crm/v1/bulk-update' REST-API endpoint in all versions up to, and including, 1.1.8. This makes it possible for unauthenticated attackers to update leads tags.

The vulnerability identified as CVE-2025-13093 affects the Devs CRM WordPress plugin, specifically targeting the REST-API endpoint at /wp-json/devs-crm/v1/bulk-update. This issue represents a critical authorization flaw that undermines the security model of the plugin and exposes sensitive data manipulation capabilities to unauthorized parties. The vulnerability exists within all versions up to and including 1.1.8, indicating a widespread exposure across the plugin's user base. The flaw manifests as a missing capability check that should normally validate user permissions before allowing data modification operations. Without proper authentication verification, the endpoint becomes accessible to any attacker who can make HTTP requests to the WordPress REST API, effectively eliminating the plugin's built-in access controls.
The technical implementation of this vulnerability stems from inadequate input validation and permission verification within the plugin's REST-API framework. When the bulk-update endpoint processes requests, it fails to verify whether the requesting entity possesses the necessary privileges to modify lead tags within the CRM system. This missing capability check creates an authentication bypass condition that allows malicious actors to perform unauthorized data modification operations. The vulnerability directly maps to CWE-863, which addresses "Incorrect Authorization" issues where the system fails to properly verify that an actor is authorized to perform a requested operation. The REST-API endpoint essentially operates without proper authentication gates, making it a prime target for automated exploitation attempts and manual attack vectors.
The operational impact of this vulnerability extends beyond simple data corruption, as it enables attackers to manipulate lead information within the CRM system. Lead tags represent critical business data that often contain sensitive customer information, marketing campaign identifiers, and sales pipeline status indicators. An attacker with access to this endpoint can modify lead tags to redirect sales leads, alter marketing priorities, or obscure important customer relationships. This capability significantly undermines the integrity of the CRM system and can lead to substantial business disruption. The vulnerability also creates potential for data exfiltration scenarios where attackers might modify tags to flag specific leads for further exploitation or manipulation. According to ATT&CK framework tactic TA0006 (Credential Access) and technique T1566 (Phishing), this vulnerability could be exploited through social engineering to gain initial access, followed by privilege escalation through the exposed API endpoint.
Mitigation strategies for this vulnerability should prioritize immediate plugin updates to versions that address the capability check deficiency. System administrators must ensure that all instances of the Devs CRM plugin are upgraded to patched versions that implement proper authentication verification for the bulk-update endpoint. Network administrators should consider implementing API rate limiting and monitoring to detect unusual patterns of bulk data modification attempts. The WordPress security hardening measures should include restricting access to REST-API endpoints through .htaccess rules or firewall configurations, particularly for endpoints that handle sensitive data operations. Security teams should also implement comprehensive monitoring of lead tag modifications to detect unauthorized changes and establish automated alerting mechanisms. Additionally, organizations should conduct thorough penetration testing to identify any other exposed API endpoints within their WordPress installations that may exhibit similar authorization flaws. The remediation process must include verification that all existing users maintain appropriate access levels and that no unauthorized modifications have occurred during the vulnerability window.
