Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1714 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.keycloak:keycloak-common (Maven): affected all versions; fixed in 11.0.0\n- org.keycloak:keycloak-common (Maven): affected all versions; fixed in 11.0.0\n- org.keycloak:keycloak-core (Maven): affected all versions; fixed in 11.0.0\n- org.keycloak:keycloak-core (Maven): affected all versions; fixed in 11.0.0\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-2020-1714/ (Markdown: https://insights.sbomify.com/CVE-2020-1714/index.md)","id":"CVE-2020-1714","markdown":"https://insights.sbomify.com/CVE-2020-1714/index.md","name":"CVE-2020-1714","record":{"aliases":["GHSA-m6mm-q862-j366","RHSA-2020:2814","RHSA-2020:2816"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Keycloak identity server","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution in Keycloak by injecting malicious serialized Java objects due to unsafe deserialization practices.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"quarkus","vendor":"quarkus"},{"product":"decision_manager","vendor":"redhat"},{"product":"jboss_fuse","vendor":"redhat"},{"product":"keycloak","vendor":"redhat"},{"product":"openshift_application_runtimes","vendor":"redhat"},{"product":"process_automation","vendor":"redhat"},{"product":"single_sign-on","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A flaw was found in Keycloak before version 11.0.0, where the code base contains usages of ObjectInputStream without type checks.
