Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-8031 in the wild and no public exploit code.\n\nAffected product: openSUSE Open Build Service. 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-2020-8031/ (Markdown: https://insights.sbomify.com/CVE-2020-8031/index.md)","id":"CVE-2020-8031","markdown":"https://insights.sbomify.com/CVE-2020-8031/index.md","name":"CVE-2020-8031","record":{"aliases":["DEBIAN-CVE-2020-8031","GHSA-6g6q-c7q8-8r7m","OESA-2022-1577","UBUNTU-CVE-2020-8031"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Open Build Service","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious JavaScript into markdown content in Open Build Service, compromising confidentiality and integrity.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[{"product":"open_build_service","vendor":"opensuse"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Open Build Service allows remote attackers to store JS code in markdown that is not properly escaped, impacting confidentiality and integrity.
