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 malicious request to the web application without their knowledge. CSRF exploits the trust that a web application places in the user's browser by leveraging the user's active session cookies or authentication tokens. In this case, the vulnerability allows attackers to perform unauthorized actions on behalf of the user, potentially modifying user data, changing configurations, or executing sensitive operations depending on the privileges of the authenticated user. The vulnerability arises due to the lack of proper anti-CSRF protections such as synchronizer tokens or strict origin checking in Casdoor 2.95.0. Although no exploits have been reported in the wild, the presence of this vulnerability poses a risk to any deployment of Casdoor that relies on user authentication for sensitive operations. The absence of patch links suggests that a fix may not yet be publicly available, increasing the urgency for organizations to apply compensating controls. Since Casdoor is an identity and access management platform, exploitation could lead to significant security breaches, including unauthorized access or privilege escalation within connected systems. The vulnerability affects web applications and requires the victim to be authenticated and visit a malicious site, which is typical for CSRF attacks.

For European organizations, the CSRF vulnerability in Casdoor 2.95.0 can compromise the integrity of user sessions and lead to unauthorized actions being executed without user consent. This can result in unauthorized changes to user permissions, exposure of sensitive identity data, or manipulation of authentication workflows. Organizations relying on Casdoor for identity management risk unauthorized account modifications or privilege escalations, potentially affecting compliance with GDPR and other data protection regulations. The impact extends to availability if critical configurations are altered or accounts are locked out. Since Casdoor is used in various sectors including government, finance, and healthcare, exploitation could disrupt critical services and erode trust. The medium severity rating reflects that while the vulnerability requires user interaction and an authenticated session, the potential damage to identity and access management systems is significant. European entities with integrated Casdoor deployments must consider the risk of targeted phishing or social engineering campaigns to exploit this vulnerability.

To mitigate the CSRF vulnerability in Casdoor 2.95.0, organizations should implement robust anti-CSRF protections such as synchronizer tokens or double-submit cookies to validate the legitimacy of requests. Enforcing strict SameSite cookie attributes (e.g., SameSite=Lax or Strict) can reduce the risk of cross-origin requests. Organizations should monitor and restrict referrer headers and implement origin checking on sensitive endpoints. Until an official patch is released, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious CSRF attempts. Educate users about phishing risks and encourage the use of multi-factor authentication to reduce the impact of compromised sessions. Regularly audit Casdoor configurations and logs for unusual activities. If possible, upgrade to a newer, patched version of Casdoor once available. Additionally, segment identity management systems to limit the blast radius of any successful exploit. Conduct penetration testing focused on CSRF to validate the effectiveness of implemented controls.
