Title
Keycloak-services: keycloak-services: uma protection api resourcetype field not validated — cross-owner resource access
Summary
A flaw was found in the UserManagedPermissionService of the Keycloak authorization server. The UMA Protection API, which manages user permissions, fails to validate the resourceType field when a user creates a new policy. This allows an attacker to create a policy that applies to resources owned by other users, potentially leading to unauthorized access or modification of sensitive data across the entire realm.

This content was generated utilizing AI tools in conjunction with data from https://cmetaxonomy.org. Customers are advised to independently evaluate and test these temporary mitigations within their own infrastructure.\n\nThe highest-value action is to enforce ownership validation on the resourceType field within UserManagedPermissionService to prevent UMA policies from attaching to resources owned by other users: upgrade to Red Hat build of Keycloak 26.4.17, 26.6.8 (or the fixed Rhbk/Keycloak Rhel/Keycloak Services builds), which validates the resourceType field during policy creation in UserManagedPermissionService to prevent policies from matching resources across different owners during evaluation in DefaultPolicyEvaluator, closing crafted UMA policy creation specifying an arbitrary victim resourceType. Until patched, this is a concern on Keycloak deployments exposing the UMA Protection API where authenticated realm users have permission to create and manage resources, so Restrict authenticated users from creating and managing resources, limit exposure of sensitive resourceType identifiers, and monitor policy definitions created via the UMA Protection API. As a compensating measure, Capture audit records when authenticated users create or modify authorization policies via the UMA Protection API to detect unauthorized cross-owner policy creation. These controls limit blast radius and contain exploitation, but they do not fix the underlying missing authorization defect \u2014 apply the upstream patch to fully remediate.\n\nHighest-impact CME: CME-1006 Privilege Change Audit Logging (medium)"

This content was generated utilizing AI tools in conjunction with data from https://cmetaxonomy.org. Customers are advised to independently evaluate and test these temporary mitigations within their own infrastructure.\n\nThe highest-value action is to enforce ownership validation on the resourceType field within UserManagedPermissionService to prevent UMA policies from attaching to resources owned by other users: upgrade to Red Hat build of Keycloak 26.4.17, 26.6.8 (or the fixed Rhbk/Keycloak Rhel/Keycloak Services builds), which validates the resourceType field during policy creation in UserManagedPermissionService to prevent policies from matching resources across different owners during evaluation in DefaultPolicyEvaluator, closing crafted UMA policy creation specifying an arbitrary victim resourceType. Until patched, this is a concern on Keycloak deployments exposing the UMA Protection API where authenticated realm users have permission to create and manage resources, so Restrict authenticated users from creating and managing resources, limit exposure of sensitive resourceType identifiers, and monitor policy definitions created via the UMA Protection API. As a compensating measure, Capture audit records when authenticated users create or modify authorization policies via the UMA Protection API to detect unauthorized cross-owner policy creation. These controls limit blast radius and contain exploitation, but they do not fix the underlying missing authorization defect \u2014 apply the upstream patch to fully remediate.\n\nHighest-impact CME: CME-1006 Privilege Change Audit Logging (medium)"

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
