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-2026-50040 in the wild and no public exploit code.\n\nAffected product: StoneFly Storage Concentrator. 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-2026-50040/ (Markdown: https://insights.sbomify.com/CVE-2026-50040/index.md)","id":"CVE-2026-50040","markdown":"https://insights.sbomify.com/CVE-2026-50040/index.md","name":"CVE-2026-50040","record":{"aliases":["GHSA-8h25-3425-5fgh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Storage Concentrator","requires_auth":"none","summary":"Reflected XSS in StoneFly Storage Concentrator allows attackers to execute scripts in authenticated users' browsers, potentially stealing sessions or performing unauthorized actions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Storage Concentrator (SC \u0026 SCVM) is vulnerable to reflected cross-site scripting due to unsanitized content being echoed back in 404 error pages.
