An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-82078 in the wild since at least 31 Aug 2026.\n\nAffected product: PaperCut MF/NG. 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-2026-82078/ (Markdown: https://insights.sbomify.com/CVE-2026-82078/index.md)","id":"CVE-2026-82078","markdown":"https://insights.sbomify.com/CVE-2026-82078/index.md","name":"CVE-2026-82078","record":{"aliases":["GHSA-mjg5-wj9r-9mfx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Print management software","requires_auth":"high_privilege","summary":"Attackers with configuration access can execute arbitrary Java bytecode via unsafe dynamic class loading in PaperCut MF/NG database connectors.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PaperCut","cpe":[{"product":"papercut_mf","vendor":"papercut"},{"product":"papercut_ng","vendor":"papercut"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-470","name":"Use of Externally-Controlled Input to Select Classes or Code"}],"description":"An unsafe dynamic class loading vulnerability exists in the database connection utilities of PaperCut MF and PaperCut NG.
