An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-0663 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-2026-0663/ (Markdown: https://insights.sbomify.com/CVE-2026-0663/index.md)","id":"CVE-2026-0663","markdown":"https://insights.sbomify.com/CVE-2026-0663/index.md","name":"CVE-2026-0663","record":{"aliases":["GHSA-grx8-c238-5vmr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Files Server","requires_auth":"high_privilege","summary":"An authenticated vault administrator can crash the M-Files Server process by calling a vulnerable API endpoint, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[{"product":"m-files_server","vendor":"m-files"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1286","name":"Improper Validation of Syntactic Correctness of Input"}],"description":"Denial-of-service vulnerability in M-Files Server versions before 26.1.15632.3 allows an authenticated attacker with vault administrator privileges to crash the M-Files Server process by calling a vulnerable API endpoint.","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":"Denial of Service condition in M-Files Server","id":"CVE-2026-0663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Royal Elementor Addons \u003c= 1.7.1049 - Authenticated (Contributor+) Stored Cross-Site Scripting via REST API Meta Bypass","id":"CVE-2026-0664"},"packages":[],"prev":{"headline":"Untrusted Search Path Vulnerability when opening max Files","id":"CVE-2026-0662"},"products":["M-Files Server"],"published":"2026-01-21","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 Corporation"]},"summary":"An authenticated vault administrator can crash the M-Files Server process by calling a vulnerable API endpoint, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-0663/"}
