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-2026-18372 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-2026-18372/ (Markdown: https://insights.sbomify.com/CVE-2026-18372/index.md)","id":"CVE-2026-18372","markdown":"https://insights.sbomify.com/CVE-2026-18372/index.md","name":"CVE-2026-18372","record":{"aliases":["GHSA-2qm2-pcpp-5p89"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Files Web","requires_auth":"high_privilege","summary":"An authenticated vault administrator can inject arbitrary CSS into M-Files Web, altering the user interface for other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"CSS injection vulnerability in M-Files Web before 26.8.16330.2 allows an authenticated vault administrator to inject arbitrary CSS, affecting the web user interface displayed to other vault users.","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":"CSS injection in M-Files Web","id":"CVE-2026-18372","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in glibc","id":"CVE-2026-18374"},"packages":[],"prev":{"headline":"HTML injection in M-Files Web","id":"CVE-2026-18371"},"products":["M-Files Web"],"published":"2026-08-19","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":"2026-08-20","vendors":["M-Files Corporation"]},"summary":"An authenticated vault administrator can inject arbitrary CSS into M-Files Web, altering the user interface for other users.","url":"https://insights.sbomify.com/CVE-2026-18372/"}
