CVE-2025-61524
7.2Casdoor · Casdoor
Casdoor v2.26.0 and earlier contains a permission bypass flaw allowing remote authenticated administrators to escalate privileges by manipulating URL structures.
Executive summary
A critical permission verification vulnerability in Casdoor allows authenticated administrators to bypass system security controls and gain unauthorized access to organization settings.
Vulnerability
The vulnerability exists within the permission verification module and the organization or application editing interface. It allows a remote authenticated administrator from any organization to bypass permission checks by directly concatenating specific URL strings after authenticating to the system.
Business impact
Successful exploitation of this flaw allows an attacker to perform administrative actions outside their authorized scope, leading to a complete compromise of the affected organization or application settings. Given the CVSS score of 7.2, this represents a high-severity risk that could result in unauthorized data modification, loss of system integrity, and potential escalation to full system control.
Remediation
Immediate Action: Update the Casdoor software to version 2.63.0 or later as provided in the vendor release.
Proactive Monitoring: Review administrative access logs for unusual URL patterns or attempts to access administrative endpoints that fall outside the typical administrative workflow for specific user accounts.
Compensating Controls: Implement strict Web Application Firewall (WAF) rules to inspect and filter incoming requests for URL manipulation patterns that attempt to bypass standard permission path validation.
Exploitation status
Public Exploit Available: Yes, a published proof-of-concept exists, attributed to the security researcher's technical write-up provided in the referenced GitHub Gist.
Analyst recommendation
This vulnerability presents a significant risk to the integrity of administrative controls within the Casdoor ecosystem. Organizations must prioritize the upgrade to version 2.63.0 to close the identified permission bypass gap. Failure to patch may allow malicious actors with existing administrative credentials to escalate their privileges and compromise the entire application environment.
