It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-6180 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-2026-6180/ (Markdown: https://insights.sbomify.com/CVE-2026-6180/index.md)","id":"CVE-2026-6180","markdown":"https://insights.sbomify.com/CVE-2026-6180/index.md","name":"CVE-2026-6180","record":{"aliases":["GHSA-hqg4-rx24-2464"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"PaperCut MF","requires_auth":"low_privilege","summary":"A race condition in PaperCut MF allows unauthorized session establishment via truncated badge IDs when custom post-processing scripts are enabled.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PaperCut","cpe":[{"product":"papercut_mf","vendor":"papercut"},{"product":"papercut_ng","vendor":"papercut"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions involving dropped packets and out-of-order sequence counters, the server may incorrectly process fragmented data chunks. If a sequence reset notification fails to reach the server, the server may reject the initial data chunk while erroneously accepting subsequent chunks before a connection reset completes.\n\nThis leads to the registration of a truncated badge ID string. While this typically results in an authentication failure, the vulnerability is compounded in environments utilizing custom badge-ID post-processing scripts. In such configurations, the truncated string may be transformed into a valid ID belonging to a different user, leading to unauthorized session establishment (Incorrect User Login) on the device.","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 MF: Card truncation on HP readers","id":"CVE-2026-6180","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in AXIS OS","id":"CVE-2026-6181"},"packages":[],"prev":{"headline":"Stored Cross Site Scripting in NightWolf Penetration Testing Platform","id":"CVE-2026-6179"},"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":"2026-05-05","vendors":["PaperCut"]},"summary":"A race condition in PaperCut MF allows unauthorized session establishment via truncated badge IDs when custom post-processing scripts are enabled.","url":"https://insights.sbomify.com/CVE-2026-6180/"}
