Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-97846 in the wild and no public exploit code.\n\nAffected product: Red Hat Build of Keycloak. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-97846/ (Markdown: https://insights.sbomify.com/CVE-2026-97846/index.md)","id":"CVE-2026-97846","markdown":"https://insights.sbomify.com/CVE-2026-97846/index.md","name":"CVE-2026-97846","record":{"aliases":["GHSA-f7cv-8449-mr73"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Identity and Access Management","requires_auth":"low_privilege","summary":"Attackers with stolen credentials can bypass mTLS holder-of-key binding in Keycloak's Standard Token Exchange V2 to obtain unrestricted tokens.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate.
