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-2018-1000821 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-1000821/ (Markdown: https://insights.sbomify.com/CVE-2018-1000821/index.md)","id":"CVE-2018-1000821","markdown":"https://insights.sbomify.com/CVE-2018-1000821/index.md","name":"CVE-2018-1000821","record":{"aliases":["GHSA-7q84-r8xm-hp4c"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SMath Studio","requires_auth":"none","summary":"Attackers can exploit XML External Entity vulnerabilities in SMath Studio files to disclose confidential data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"micromathematics","vendor":"micromathematics_project"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"MicroMathematics version before commit 5c05ac8 contains a XML External Entity (XXE) vulnerability in SMathStudio files that can result in Disclosure of confidential data, denial of service, SSRF, port scanning.
