CVE-2025-70150 identifies a critical security vulnerability in the CodeAstro Membership Management System version 1.0. The vulnerability exists in the delete_members.php endpoint, which lacks any authentication mechanism to verify the identity or permissions of the requester. This missing authentication (CWE-862) allows an unauthenticated attacker to invoke the script and delete arbitrary member records by supplying the targeted member's id parameter. The vulnerability is remotely exploitable over the network without any user interaction or privileges, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is severe, affecting confidentiality, integrity, and availability (all rated high), since unauthorized deletion of member data compromises data integrity and availability, and potentially exposes sensitive membership information. No patches or fixes have been published yet, and no known exploits are reported in the wild, but the vulnerability's nature and critical severity score (9.8) make it a high-risk issue. The vulnerability highlights a fundamental security design flaw where critical operations are exposed without access control, making it trivial for attackers to disrupt membership data and organizational operations.

For European organizations using CodeAstro Membership Management System 1.0, this vulnerability poses a significant risk of unauthorized data deletion, leading to loss of critical member information. This can disrupt business operations, cause loss of trust among members, and potentially violate data protection regulations such as GDPR due to unauthorized data manipulation. The integrity and availability of membership data are directly compromised, which can affect organizations relying on accurate member records for service delivery, billing, or compliance. Additionally, the lack of authentication means attackers can exploit this vulnerability remotely without any credentials, increasing the attack surface. Organizations may face operational downtime, financial losses, and reputational damage if exploited. The absence of known exploits currently provides a window for proactive mitigation, but the critical severity demands urgent attention.

1. Immediately restrict access to the delete_members.php script by implementing network-level controls such as IP whitelisting or firewall rules to limit access to trusted administrators only. 2. Implement robust authentication and authorization checks in the application code to ensure only authenticated and authorized users can perform member deletions. 3. Conduct a thorough code review of all critical endpoints to identify and remediate similar missing authentication issues. 4. Monitor application logs for unusual or unauthorized deletion attempts to detect potential exploitation early. 5. Develop and deploy patches or updates that enforce proper access controls on the vulnerable endpoint as soon as they become available. 6. Educate development teams on secure coding practices, emphasizing the importance of authentication and authorization for sensitive operations. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the delete_members.php endpoint. 8. Regularly back up membership data to enable recovery in case of data deletion or corruption.
