CVE-2025-12202 is a Cross-Site Request Forgery (CSRF) vulnerability found in the ajayrandhawa User-Management-PHP-MYSQL web application, identified by a specific commit hash rather than a traditional version number due to the product's continuous delivery and rolling release model. The vulnerability allows remote attackers to induce authenticated users to submit forged requests, potentially leading to unauthorized actions within the user management system. The attack vector requires no authentication or privileges on the attacker’s part but does require user interaction, such as clicking a malicious link or visiting a crafted webpage. The CVSS 4.0 base score is 5.3 (medium severity), reflecting the network attack vector, low complexity, no privileges required, but requiring user interaction and causing limited integrity impact without affecting confidentiality or availability. The vendor was contacted early but has not responded, and no patches or version updates have been published. The exploit code has been publicly released, increasing the risk of exploitation despite no current reports of active attacks. The vulnerability could allow attackers to manipulate user management functions, such as changing user roles, deleting users, or altering permissions, thereby compromising the integrity of the affected system. Given the widespread use of PHP and MySQL in web applications, this vulnerability poses a tangible risk to organizations relying on this user management solution, especially where sensitive user data or administrative controls are involved.

For European organizations, exploitation of this CSRF vulnerability could lead to unauthorized modifications in user management workflows, potentially allowing attackers to escalate privileges, delete or modify user accounts, or alter access controls. This undermines the integrity of user data and could indirectly affect confidentiality if unauthorized users gain elevated access. Although availability is not directly impacted, the trustworthiness and security posture of affected systems would be compromised. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely on PHP-MySQL based user management systems are particularly at risk. The public availability of exploit code increases the likelihood of opportunistic attacks, especially in environments lacking robust CSRF protections. The lack of vendor response and absence of patches exacerbate the risk, requiring organizations to implement compensating controls promptly. Failure to address this vulnerability could result in regulatory non-compliance under GDPR if personal data is improperly accessed or modified, leading to potential legal and reputational consequences.

European organizations using the ajayrandhawa User-Management-PHP-MYSQL web application should immediately implement the following mitigations: 1) Employ anti-CSRF tokens in all state-changing requests to ensure that requests originate from legitimate users; 2) Enforce SameSite cookie attributes (preferably 'Strict' or 'Lax') to reduce the risk of CSRF via cross-site requests; 3) Implement user interaction confirmations for sensitive actions, such as multi-factor authentication or secondary validation steps; 4) Restrict HTTP methods to only those necessary (e.g., disallow GET requests for state-changing operations); 5) Monitor web server logs and application behavior for unusual or unauthorized user management activities; 6) If possible, isolate the user management application behind a web application firewall (WAF) with rules designed to detect and block CSRF attack patterns; 7) Educate users about the risks of clicking unknown links and visiting untrusted websites; 8) Consider migrating to alternative user management solutions with active vendor support and security maintenance if patching is not forthcoming; 9) Regularly audit and review user permissions and roles to detect unauthorized changes; 10) Engage in vulnerability scanning and penetration testing focused on CSRF and related web application security issues.
