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-2019-18873 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-2019-18873/ (Markdown: https://insights.sbomify.com/CVE-2019-18873/index.md)","id":"CVE-2019-18873","markdown":"https://insights.sbomify.com/CVE-2019-18873/index.md","name":"CVE-2019-18873","record":{"aliases":["GHSA-pw8j-fmq7-g3jm"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"FUDForum","requires_auth":"low_privilege","summary":"Stored XSS in FUDForum allows attackers to execute arbitrary code and compromise the server when an admin views user details.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fudforum","vendor":"fudforum"}],"cvss":{"score":9,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"FUDForum 3.0.9 is vulnerable to Stored XSS via the User-Agent HTTP header.
