Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16071 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- keycloak (Bitnami): affected from 26.4.0; fixed in 26.4.14, 26.6.5\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-16071/ (Markdown: https://insights.sbomify.com/CVE-2026-16071/index.md)","id":"CVE-2026-16071","markdown":"https://insights.sbomify.com/CVE-2026-16071/index.md","name":"CVE-2026-16071","record":{"aliases":["BIT-keycloak-2026-16071","GHSA-m28w-c4hx-9fvg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity provider","requires_auth":"low_privilege","summary":"A delegated administrator can bypass LDAP search boundaries to read unauthorized directory data and import users, affecting Keycloak deployments.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"build_of_keycloak","vendor":"redhat"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-90","name":"Improper Neutralization of Special Elements used in an LDAP Query"}],"description":"A flaw was found in the LDAP storage provider of Keycloak, which is used to federate user identities from external directories.
