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-2022-4270 in the wild and no public exploit code.\n\nAffected product: M-Files Web. 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-2022-4270/ (Markdown: https://insights.sbomify.com/CVE-2022-4270/index.md)","id":"CVE-2022-4270","markdown":"https://insights.sbomify.com/CVE-2022-4270/index.md","name":"CVE-2022-4270","record":{"aliases":["GHSA-fh2m-jrq8-h6q5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Files Web","requires_auth":"high_privilege","summary":"Incorrect privilege assignment in M-Files Web allows attackers to accidentally change permissions, potentially escalating privileges.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[{"product":"m-files_server","vendor":"m-files"}],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Incorrect privilege assignment issue in M-Files Web in M-Files Web versions before 22.5.11436.1 could have changed permissions accidentally.","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 privilege assignment in M-Files Web Server","id":"CVE-2022-4270","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site Scripting (XSS) - Reflected in osticket/osticket","id":"CVE-2022-4271"},"packages":[],"prev":{"headline":"Denial of service in Linux kernel (TC subsystem)","id":"CVE-2022-4269"},"products":["M-Files Web"],"published":"2022-12-02","related":[{"cvss_score":9.2,"headline":"Support for authentication bypass condition in M-Files LDAP authentication","id":"CVE-2024-10127","kev_date_added":null,"published":"2024-11-20"},{"cvss_score":8.4,"headline":"Path traversal in M-Files API","id":"CVE-2025-5964","kev_date_added":null,"published":"2025-06-15"},{"cvss_score":8.4,"headline":"Path traversal in M-Files API","id":"CVE-2024-6789","kev_date_added":null,"published":"2024-08-27"},{"cvss_score":7.5,"headline":"Denial of service condition in M-Files Server","id":"CVE-2024-4056","kev_date_added":null,"published":"2024-04-26"},{"cvss_score":7.5,"headline":"Brute force vulnerability in M-Files user authentication","id":"CVE-2023-6912","kev_date_added":null,"published":"2023-12-20"},{"cvss_score":7.5,"headline":"Denial of service condition in M-Files Server","id":"CVE-2023-3405","kev_date_added":null,"published":"2023-06-27"},{"cvss_score":7.5,"headline":"Uncontrolled Resource Consuption in M-Files Server","id":"CVE-2023-0383","kev_date_added":null,"published":"2023-04-20"}],"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":"Incorrect privilege assignment in M-Files Web allows attackers to accidentally change permissions, potentially escalating privileges.","url":"https://insights.sbomify.com/CVE-2022-4270/"}
