Name of the Vulnerable Software and Affected Versions
Keycloak (affected versions not specified)
Description
A flaw exists in Keycloak where an authenticated user possessing the uma protection role can circumvent User-Managed Access (UMA) policy validation. This allows an attacker to include resource identifiers belonging to other users within a policy creation request, even when the URL path indicates a resource owned by the attacker. This results in the attacker obtaining unauthorized permissions to resources owned by other users, enabling them to acquire a Requesting Party Token (RPT) and potentially access sensitive information or execute unauthorized actions.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
