Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-9497 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.mengyun:tcc-transaction (Maven): affected all versions up to 2.1.0; no fix listed\n- org.mengyun:tcc-transaction (Maven): affected all versions up to 2.1.0; no fix listed\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-2026-9497/ (Markdown: https://insights.sbomify.com/CVE-2026-9497/index.md)","id":"CVE-2026-9497","markdown":"https://insights.sbomify.com/CVE-2026-9497/index.md","name":"CVE-2026-9497","record":{"aliases":["GHSA-4r4v-3jc5-hrg9"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java transaction library","requires_auth":"low_privilege","summary":"Remote attackers can exploit unsafe Fastjson deserialization in tcc-transaction to execute arbitrary code.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A flaw has been found in changmingxie tcc-transaction up to 2.1.0.
