CVE-2025-13093 identifies a missing authorization vulnerability (CWE-862) in the ajitdas Devs CRM – Manage tasks, attendance and teams all together WordPress plugin. The vulnerability exists in the REST API endpoint '/wp-json/devs-crm/v1/bulk-update', which lacks proper capability checks, allowing unauthenticated attackers to perform bulk updates on lead tags. This means that any attacker can modify CRM data without needing credentials or user interaction, compromising data integrity. The vulnerability affects all versions up to 1.1.8 of the plugin. The CVSS 3.1 score is 5.3 (medium), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), integrity impact (I:L), and no availability impact (A:N). No patches or known exploits are currently available, but the flaw presents a risk for unauthorized data manipulation, potentially disrupting business processes relying on accurate CRM data. The vulnerability is publicly disclosed and should be addressed promptly to prevent exploitation.

For European organizations, especially SMEs and enterprises relying on WordPress-based CRM solutions, this vulnerability could lead to unauthorized modification of customer data, specifically lead tags. While it does not expose confidential information or cause service outages, the integrity compromise can disrupt marketing, sales, and customer management workflows, leading to misinformed business decisions or reputational damage. Attackers could manipulate lead data to skew analytics or sabotage campaigns. Since the vulnerability requires no authentication and can be exploited remotely, it poses a significant risk to organizations with publicly accessible WordPress sites using the affected plugin. The impact is more pronounced in sectors where CRM data accuracy is critical, such as finance, retail, and professional services. Additionally, regulatory compliance issues may arise if data integrity controls are mandated under GDPR or other frameworks.

Immediate mitigation involves restricting access to the vulnerable REST API endpoint by implementing web application firewall (WAF) rules to block unauthenticated requests to '/wp-json/devs-crm/v1/bulk-update'. Organizations should monitor API logs for unusual bulk update activity and implement rate limiting to reduce exploitation risk. Until an official patch is released, disabling or removing the Devs CRM plugin is advisable if feasible. Administrators should ensure WordPress core and all plugins are kept up to date and subscribe to security advisories from the vendor and WordPress security communities. Employing strong network segmentation and limiting public exposure of administrative endpoints can further reduce risk. Post-patch, verify that capability checks are enforced on all REST API endpoints. Conduct regular audits of CRM data integrity to detect unauthorized changes promptly.
