An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-6418 in the wild and no public exploit code.\n\nAffected product: PaperCut NG/MF. 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-2026-6418/ (Markdown: https://insights.sbomify.com/CVE-2026-6418/index.md)","id":"CVE-2026-6418","markdown":"https://insights.sbomify.com/CVE-2026-6418/index.md","name":"CVE-2026-6418","record":{"aliases":["GHSA-mhwr-j844-q9pq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"PaperCut NG/MF","requires_auth":"high_privilege","summary":"Administrative users can exploit path traversal in Shared Account Synchronization to read arbitrary local files and disclose sensitive system information.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PaperCut","cpe":[{"product":"papercut_mf","vendor":"papercut"},{"product":"papercut_ng","vendor":"papercut"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-552","name":"Files or Directories Accessible to External Parties"},{"id":"CWE-36","name":"Absolute Path Traversal"}],"description":"An issue was discovered in the Shared Account Synchronization component of PaperCut MF (version 25.0.4). The application allows administrative users to configure a source path for account data synchronization.\n\nDue to a lack of proper path validation and sanitization, an authenticated user with administrative privileges can specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files.\n\nWhen the synchronization process is triggered, the application attempts to parse the contents of the specified file, subsequently exposing the data within the application's account management interface. This vulnerability could lead to the disclosure of sensitive system information or configuration details, depending on the permissions of the service account under which the application is running.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"PaperCut NG/MF: Path Traversal in Shared Account Synchronization","id":"CVE-2026-6418","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Wishlist Member","id":"CVE-2026-6419"},"packages":[],"prev":{"headline":"GLS Shipping for WooCommerce \u003c= 1.4.0 - Reflected Cross-Site Scripting via 'failed_orders'","id":"CVE-2026-6417"},"products":["PaperCut NG/MF"],"published":"2026-05-05","related":[{"cvss_score":9.8,"headline":"PaperCut MF/NG Improper Access Control","id":"CVE-2023-27350","kev_date_added":"2023-04-21","published":"2023-04-20"},{"cvss_score":9.4,"headline":"PaperCut NG/MF Unsafe Reflection","id":"CVE-2026-82078","kev_date_added":"2026-08-31","published":"2026-08-28"},{"cvss_score":8.8,"headline":"PaperCut NG/MF Missing Authentication for Critical Function","id":"CVE-2026-81578","kev_date_added":"2026-08-31","published":"2026-08-28"},{"cvss_score":8.4,"headline":"PaperCut NG/MF Cross-Site Request Forgery (CSRF)","id":"CVE-2023-2533","kev_date_added":"2025-07-28","published":"2023-06-20"},{"cvss_score":8.2,"headline":"PaperCut NG/MF Improper Authentication","id":"CVE-2023-27351","kev_date_added":"2026-04-20","published":"2023-04-20"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2023-39143","kev_date_added":null,"published":"2023-08-04"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2019-12135","kev_date_added":null,"published":"2019-06-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-16","vendors":["PaperCut"]},"summary":"Administrative users can exploit path traversal in Shared Account Synchronization to read arbitrary local files and disclose sensitive system information.","url":"https://insights.sbomify.com/CVE-2026-6418/"}
