# CVE-2026-1486: Org.keycloak.protocol.oidc.grants: disabled identity providers are still accepted for jwt authorization grant

## What is CVE-2026-1486?

CVE-2026-1486 is a high-severity authentication bypass vulnerability in Red Hat build of Keycloak 26.4, published on 9 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A flaw was found in Keycloak. A vulnerability exists in the jwt-authorization-grant flow where the server fails to verify if an Identity Provider (IdP) is enabled before issuing tokens. The issuer lookup mechanism (lookupIdentityProviderFromIssuer) retrieves the IdP configuration but does not filter for isEnabled=false. If an administrator disables an IdP (e.g., due to a compromise or offboarding), an entity possessing that IdP's signing key can still generate valid JWT assertions that Keycloak accepts, resulting in the issuance of valid access tokens.

Weakness: CWE-358 (Improperly Implemented Security Check for Standard)

Exploitation: There is no known exploitation of CVE-2026-1486 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 26.4.9
- org.keycloak:keycloak-services (Maven): affected all versions; fixed in 26.4.9
- org.keycloak:keycloak-services (Maven): affected from 26.5.0; fixed in 26.5.3

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
