It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18490 in the wild and no public exploit code.\n\nAffected product: Ibm Financial Transaction Manager. 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-2026-18490/ (Markdown: https://insights.sbomify.com/CVE-2026-18490/index.md)","id":"CVE-2026-18490","markdown":"https://insights.sbomify.com/CVE-2026-18490/index.md","name":"CVE-2026-18490","record":{"aliases":["GHSA-5p47-frcm-v44p"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM Financial Transaction Manager","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code via Java deserialization in IBM FTM, exposing credentials and allowing manipulation of payment rules.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"financial_transaction_manager","vendor":"ibm"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to unauthenticated remote code execution via Java native deserialization on the PayDir Business Rules Manager RMI SSL endpoint (BrmRMISSLServerSocketFactory.java:95, EP8).
