An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-12040 in the wild and no public exploit code.\n\nAffected product: Sensiolabs Symfony. 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-2018-12040/ (Markdown: https://insights.sbomify.com/CVE-2018-12040/index.md)","id":"CVE-2018-12040","markdown":"https://insights.sbomify.com/CVE-2018-12040/index.md","name":"CVE-2018-12040","record":{"aliases":["DEBIAN-CVE-2018-12040","GHSA-mjcw-3g32-5p52"],"analysis":{"component_type":"library","fix_type":"configuration_change","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Symfony web profiler","requires_auth":"none","summary":"Reflected XSS in Symfony's web profiler allows script injection via the file parameter, requiring the profiler to be enabled in production.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"symfony","vendor":"sensiolabs"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Reflected Cross-site scripting (XSS) vulnerability in the web profiler in SensioLabs Symfony 3.3.6 allows remote attackers to inject arbitrary web script or HTML via the \"file\" parameter, aka an _profiler/open?file= URI.
