Title
Org.keycloak.services.resources.organizations: keycloak: unauthorized organization registration via improper invitation token validation
Summary
A flaw was found in Keycloak. An attacker can exploit this vulnerability by modifying the organization ID and target email within a legitimate invitation token's JSON Web Token (JWT) payload. This lack of cryptographic signature verification allows the attacker to successfully self-register into an unauthorized organization, leading to unauthorized access.

Title
Keycloak: incorrect ownership checks in /uma-policy/
Summary
A flaw was found in Keycloak. A significant Broken Access Control vulnerability exists in the UserManagedPermissionService (UMA Protection API). When updating or deleting a UMA policy associated with multiple resources, the authorization check only verifies the caller's ownership against the first resource in the policy's list. This allows a user (Owner A) who owns one resource (RA) to update a shared policy and modify authorization rules for other resources (e.g., RB) in that same policy, even if those other resources are owned by a different user (Owner B). This constitutes a horizontal privilege escalation.

When updating or deleting a UMA policy associated with multiple resources, the authorization check only verifies the caller\u0027s ownership against the first resource in the policy\u0027s list. This allows a user (Owner A) who owns one resource (RA) to update a shared policy and modify authorization rules for other resources (e.g., RB) in that same policy, even if those other resources are owned by a different user (Owner B). This constitutes a horizontal privilege escalation."

Title
Org.keycloak.services.resources.organizations: keycloak: unauthorized organization registration via improper invitation token validation
Summary
A flaw was found in Keycloak. An attacker can exploit this vulnerability by modifying the organization ID and target email within a legitimate invitation token's JSON Web Token (JWT) payload. This lack of cryptographic signature verification allows the attacker to successfully self-register into an unauthorized organization, leading to unauthorized access.
Severity ?
8.1 (High)
CWE
- CWE-347 - Improper Verification of Cryptographic Signature
