Casdoor 2.95.0 suffers from a Cross-Site Request Forgery (CSRF) vulnerability, a common web security issue where an attacker tricks an authenticated user into submitting a forged HTTP request to the vulnerable application. This can result in unauthorized commands being executed on behalf of the user, potentially altering account settings, permissions, or other sensitive data managed by Casdoor. CSRF attacks exploit the trust a web application places in the user's browser, leveraging the user's active session to perform actions without their knowledge. The vulnerability indicates that Casdoor 2.95.0 lacks adequate CSRF protections such as anti-CSRF tokens or proper validation of the HTTP request origin. While no specific affected versions are listed beyond 2.95.0, and no patches or known exploits are currently documented, the presence of this vulnerability poses a risk to any deployment of this version. Casdoor is an identity and access management platform used to handle authentication and authorization, making it a critical component in securing web applications. Exploitation could lead to unauthorized changes in user roles, permissions, or other security-critical configurations. The absence of a CVSS score necessitates an assessment based on the vulnerability's characteristics: it impacts integrity and potentially confidentiality, requires the victim to be authenticated but does not require user interaction beyond visiting a malicious site, and affects all systems running the vulnerable version. These factors collectively suggest a medium severity level.

For European organizations, the CSRF vulnerability in Casdoor 2.95.0 can lead to unauthorized actions being performed within identity and access management systems, potentially compromising user account integrity and access controls. This could result in privilege escalation, unauthorized data access, or disruption of authentication workflows. Organizations relying on Casdoor for critical authentication services may face increased risk of account takeover or unauthorized configuration changes, undermining trust in their security posture. The impact is particularly significant for sectors with stringent access control requirements such as finance, healthcare, and government services. Additionally, the vulnerability could be leveraged as a stepping stone for further attacks within an organization's network. Although no active exploits are reported, the ease of exploitation inherent to CSRF attacks means that attackers could develop exploits rapidly once the vulnerability is publicly known. This risk underscores the importance of timely mitigation to prevent potential breaches and maintain compliance with European data protection regulations like GDPR.

To mitigate the CSRF vulnerability in Casdoor 2.95.0, organizations should implement anti-CSRF tokens in all state-changing HTTP requests to ensure that requests originate from legitimate users. Validate the HTTP Referer and Origin headers to confirm requests come from trusted sources. Employ SameSite cookie attributes to restrict cookie transmission in cross-site contexts. Ensure that all authentication and authorization endpoints enforce strict session management and verify user intent before processing sensitive actions. Regularly update Casdoor to the latest version once patches addressing this vulnerability are released. Conduct thorough security testing, including automated scanning and manual penetration testing, focusing on CSRF protections. Educate developers and administrators on secure coding practices related to web authentication and session management. Additionally, monitor web application logs for unusual or suspicious activity that may indicate attempted exploitation. For critical systems, consider implementing multi-factor authentication and anomaly detection to further reduce risk.
