Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-49103 in the wild and no public exploit code.\n\nAffected product: Webmin. 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-2026-49103/ (Markdown: https://insights.sbomify.com/CVE-2026-49103/index.md)","id":"CVE-2026-49103","markdown":"https://insights.sbomify.com/CVE-2026-49103/index.md","name":"CVE-2026-49103","record":{"aliases":["GHSA-6m8g-7xrr-8q5f"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Webmin web interface","requires_auth":"low_privilege","summary":"An attacker can exploit unsafe filename construction in Webmin's mailboxes component to read or modify arbitrary files via path traversal.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-24","name":"Path Traversal: '../filedir'"}],"description":"Webmin before 2.640 does not safely construct a filename for saving of an attachment within the mailboxes component.
