CVE-2025-58918 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Waituk Entrada WordPress theme, affecting versions up to 5.7.7. CSRF vulnerabilities occur when a web application does not adequately verify that requests made to it originate from legitimate users, allowing attackers to trick authenticated users into performing unintended actions. In this case, the Entrada theme lacks sufficient CSRF protections, such as anti-CSRF tokens (nonces), enabling an attacker to craft malicious web pages or links that, when visited by an authenticated user, cause the user’s browser to send unauthorized requests to the vulnerable site. The vulnerability is exploitable remotely over the network without requiring prior authentication, but it does require user interaction (e.g., clicking a link or visiting a malicious page). The impact primarily affects the integrity of the website, as attackers can induce changes or actions that the user did not intend, though confidentiality and availability remain unaffected. The CVSS 3.1 base score is 4.3, reflecting a medium severity level due to the ease of exploitation combined with limited impact scope. No patches or known exploits are currently available, indicating that the vulnerability is newly disclosed and unmitigated. Organizations using the Entrada theme should assess their exposure and implement compensating controls until an official patch is released.

For European organizations, this CSRF vulnerability poses a risk to the integrity of websites running the Waituk Entrada theme, particularly those relying on WordPress for content management. Attackers could leverage this flaw to perform unauthorized actions such as changing site settings, modifying content, or triggering administrative functions without the user’s consent. While the vulnerability does not directly compromise sensitive data confidentiality or cause denial of service, unauthorized changes can damage brand reputation, disrupt business operations, or facilitate further attacks. Public-facing websites, especially those with logged-in users who have elevated privileges, are at higher risk. The lack of authentication requirement for exploitation increases the attack surface, as any attacker can attempt to lure users into triggering malicious requests. European organizations with significant online presence, including e-commerce, government portals, and media sites, could face reputational damage and operational challenges if exploited. The absence of known exploits in the wild provides a window for proactive mitigation, but the medium severity rating necessitates timely action to prevent potential abuse.

1. Immediately review and implement CSRF protections in the Entrada theme or any customizations, including the use of nonce tokens for all state-changing requests. 2. Restrict sensitive actions to POST requests and validate the HTTP Referer header where feasible to ensure requests originate from trusted sources. 3. Monitor user activity logs for unusual or unauthorized actions that could indicate exploitation attempts. 4. Educate users, especially administrators, about the risks of clicking unknown links or visiting untrusted websites while authenticated. 5. Employ Web Application Firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting WordPress themes. 6. Regularly update WordPress core, themes, and plugins, and apply patches promptly once available from the vendor. 7. Consider implementing Content Security Policy (CSP) headers to reduce the risk of malicious content injection. 8. Conduct security audits and penetration testing focused on CSRF and related vulnerabilities in the web environment. 9. If possible, temporarily limit administrative access or require multi-factor authentication to reduce the impact of potential CSRF exploitation. 10. Engage with the vendor or security community to track patch releases and vulnerability disclosures related to Entrada.
