It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-26631 in the wild and no public exploit code.\n\nAffected product: Hometory Co.,Ltd Mangboard commerce package. 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-2021-26631/ (Markdown: https://insights.sbomify.com/CVE-2021-26631/index.md)","id":"CVE-2021-26631","markdown":"https://insights.sbomify.com/CVE-2021-26631/index.md","name":"CVE-2021-26631","record":{"aliases":["GHSA-rrmq-wq3p-q78r"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mangboard commerce package","requires_auth":"none","summary":"Remote attackers can manipulate order amounts to negative values to bypass payment, affecting Mangboard commerce package users.","user_interaction":"required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"commerce","vendor":"mangboard"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper input validation vulnerability in Mangboard commerce package could lead to occur for abnormal request.
