An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-4861 in the wild and no public exploit code.\n\nAffected product: M-Files Client. 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-2022-4861/ (Markdown: https://insights.sbomify.com/CVE-2022-4861/index.md)","id":"CVE-2022-4861","markdown":"https://insights.sbomify.com/CVE-2022-4861/index.md","name":"CVE-2022-4861","record":{"aliases":["GHSA-qx2w-wx28-8mhv"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Files Client","requires_auth":"high_privilege","summary":"A flaw in the authentication protocol allows high-privileged users to obtain other users' tokens, enabling unauthorized access to resources.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[{"product":"m-files_client","vendor":"m-files"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"},{"id":"CWE-303","name":"Incorrect Implementation of Authentication Algorithm"}],"description":"Incorrect implementation in authentication protocol in M-Files Client before 22.5.11356.0 allows high privileged user to get other users tokens to another resource.","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":"Incorrect Implementation of Authentication Algorithm","id":"CVE-2022-4861","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"XSS vulnerability in M-Files Web","id":"CVE-2022-4862"},"packages":[],"prev":{"headline":"KBase Metrics methods_upload_user_stats.py upload_user_data sql injection","id":"CVE-2022-4860"},"products":["M-Files Client"],"published":"2022-12-30","related":[],"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":"2026-02-23","vendors":["M-Files"]},"summary":"A flaw in the authentication protocol allows high-privileged users to obtain other users' tokens, enabling unauthorized access to resources.","url":"https://insights.sbomify.com/CVE-2022-4861/"}
