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-2026-108121 in the wild and no public exploit code.\n\nAffected product: Koozali SME 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-2026-108121/ (Markdown: https://insights.sbomify.com/CVE-2026-108121/index.md)","id":"CVE-2026-108121","markdown":"https://insights.sbomify.com/CVE-2026-108121/index.md","name":"CVE-2026-108121","record":{"aliases":["GHSA-2pfr-4hx7-3p8p"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SME Server","requires_auth":"high_privilege","summary":"High-privilege attackers can inject Apache directives during domain creation to corrupt configuration and cause a web server denial of service.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:L/VA:H/SC:N/SI:L/SA:H/E:P/S:P/AU:Y/R:A/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-96","name":"Improper Neutralization of Directives in Statically Saved Code"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Brian Mariani from DigitalCanion SA has discovered a  vulnerability in the domain creation functionality of koozali's \nSME Server version 11.0rc1-215, allowing an attacker with high privileges \nto inject reserved Apache configuration directives, corrupting \nhttpd.conf and preventing Apache from starting after a server reboot, \nresulting in a denial-of-service (DoS) condition affecting the web \nserver and its hosted virtual hosts.","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":"Koozali - SME Server Improper Input Validation in domain Creation Leads to Denial of Service","id":"CVE-2026-108121","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in WP Booking System – Booking Calendar","id":"CVE-2026-108123"},"packages":[],"prev":{"headline":"path traversal inKoozali - SME Server","id":"CVE-2026-108120"},"products":["SME Server"],"published":"2026-10-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-19","vendors":["Koozali"]},"summary":"High-privilege attackers can inject Apache directives during domain creation to corrupt configuration and cause a web server denial of service.","url":"https://insights.sbomify.com/CVE-2026-108121/"}
