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-2021-3509 in the wild and no public exploit code.\n\nAffected product: ceph-dashboard. 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-2021-3509/ (Markdown: https://insights.sbomify.com/CVE-2021-3509/index.md)","id":"CVE-2021-3509","markdown":"https://insights.sbomify.com/CVE-2021-3509/index.md","name":"CVE-2021-3509","record":{"aliases":["DEBIAN-CVE-2021-3509","GHSA-g9cr-7jh8-qrmx","UBUNTU-CVE-2021-3509"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ceph Storage Dashboard","requires_auth":"none","summary":"An XSS vulnerability in the Ceph Dashboard allows attackers to access JWT tokens exposed in documentation responses, compromising confidentiality, integrity, and availability.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ceph_storage","vendor":"redhat"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A flaw was found in Red Hat Ceph Storage 4, in the Dashboard component.
