An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-1851 in the wild and no public exploit code.\n\nAffected product: Ibm Websphere Application Server. 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-2018-1851/ (Markdown: https://insights.sbomify.com/CVE-2018-1851/index.md)","id":"CVE-2018-1851","markdown":"https://insights.sbomify.com/CVE-2018-1851/index.md","name":"CVE-2018-1851","record":{"aliases":["GHSA-mv84-hf34-fgc6"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WebSphere Application Server","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on IBM WebSphere Application Server Liberty via improper deserialization in the OpenID Connect RP service.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"websphere_application_server","vendor":"ibm"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.0/A:L/AC:L/AV:N/C:L/I:L/PR:N/S:U/UI:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"IBM WebSphere Application Server Liberty OpenID Connect could allow a remote attacker to execute arbitrary code on the system, caused by improper deserialization.
