Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-41809 in the wild and no public exploit code.\n\nAffected product: M-Files Server. 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-2021-41809/ (Markdown: https://insights.sbomify.com/CVE-2021-41809/index.md)","id":"CVE-2021-41809","markdown":"https://insights.sbomify.com/CVE-2021-41809/index.md","name":"CVE-2021-41809","record":{"aliases":["GHSA-wrw2-8vg5-g3jj"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Files Server","requires_auth":"low_privilege","summary":"Attackers can exploit a preview function to force the M-Files Server to make unauthorized external requests, potentially accessing internal resources.","user_interaction":"required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[{"product":"m-files_server","vendor":"m-files"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"SSRF vulnerability in M-Files Server products with versions before 22.1.11017.1, in a preview function allowed making queries from the server with certain document types referencing external entities.","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":"SSRF vulnerability in M-Files Server products with versions before 22.1.11017.1, allows requests from server.","id":"CVE-2021-41809","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Script injection in M-Files Admin","id":"CVE-2021-41810"},"packages":[],"prev":{"headline":"Information disclosure in M-Files Server","id":"CVE-2021-41808"},"products":["M-Files Server"],"published":"2022-01-18","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-02-23","vendors":["M-Files"]},"summary":"Attackers can exploit a preview function to force the M-Files Server to make unauthorized external requests, potentially accessing internal resources.","url":"https://insights.sbomify.com/CVE-2021-41809/"}
