Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-39152 exists.\n\nAffected packages and fixed versions:\n- com.thoughtworks.xstream:xstream (Maven): affected all versions; fixed in 1.4.18\n- com.thoughtworks.xstream:xstream (Maven): affected all versions; fixed in 1.4.18\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-2021-39152/ (Markdown: https://insights.sbomify.com/CVE-2021-39152/index.md)","id":"CVE-2021-39152","markdown":"https://insights.sbomify.com/CVE-2021-39152/index.md","name":"CVE-2021-39152","record":{"aliases":["DEBIAN-CVE-2021-39152","GHSA-xw4p-crpj-vjx2","UBUNTU-CVE-2021-39152"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java XML serialization library","requires_auth":"low_privilege","summary":"Remote attackers can access internal resources via SSRF in XStream when using default security settings on Java 8-14.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"snapmanager","vendor":"netapp"},{"product":"business_activity_monitoring","vendor":"oracle"},{"product":"commerce_guided_search","vendor":"oracle"},{"product":"communications_billing_and_revenue_management_elastic_charging_engine","vendor":"oracle"},{"product":"communications_cloud_native_core_automated_test_suite","vendor":"oracle"},{"product":"communications_cloud_native_core_binding_support_function","vendor":"oracle"},{"product":"communications_cloud_native_core_policy","vendor":"oracle"},{"product":"communications_unified_inventory_management","vendor":"oracle"},{"product":"retail_xstore_point_of_service","vendor":"oracle"},{"product":"utilities_framework","vendor":"oracle"},{"product":"utilities_testing_accelerator","vendor":"oracle"},{"product":"webcenter_portal","vendor":"oracle"},{"product":"xstream","vendor":"xstream"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"XStream is a simple library to serialize objects to XML and back again.
