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-2023-4479 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-2023-4479/ (Markdown: https://insights.sbomify.com/CVE-2023-4479/index.md)","id":"CVE-2023-4479","markdown":"https://insights.sbomify.com/CVE-2023-4479/index.md","name":"CVE-2023-4479","record":{"aliases":["GHSA-r32c-fmcr-34r3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"M-Files Web","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary scripts in users' browsers by storing malicious HTML documents in M-Files Web.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[{"product":"m-files","vendor":"m-files"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Stored XSS Vulnerability in M-Files Web versions before 23.8 allows attacker to execute script on users browser via stored HTML document within limited time period.","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":"Stored XSS Vulnerability in M-Files Web","id":"CVE-2023-4479","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Arbitrary File Read in Fusion File Manager","id":"CVE-2023-4480"},"packages":[],"prev":{"headline":"Parameter tampering in the registration resulting in blocked accounts to be created","id":"CVE-2023-4478"},"products":["M-Files Web"],"published":"2024-03-04","related":[{"cvss_score":8.8,"headline":"Local Elevation of Privilege in M-Files","id":"CVE-2023-0213","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":7.5,"headline":"Elevation of Privilege in M-Files Desktop Client","id":"CVE-2023-2480","kev_date_added":null,"published":"2023-05-25"},{"cvss_score":6.5,"headline":"Incorrect privilege assignment in M-Files Web Server","id":"CVE-2022-4264","kev_date_added":null,"published":"2022-12-09"}],"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 attacker can execute arbitrary scripts in users' browsers by storing malicious HTML documents in M-Files Web.","url":"https://insights.sbomify.com/CVE-2023-4479/"}
