An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-30186 exists.\n\nAffected product: n/a. 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-2023-30186/ (Markdown: https://insights.sbomify.com/CVE-2023-30186/index.md)","id":"CVE-2023-30186","markdown":"https://insights.sbomify.com/CVE-2023-30186/index.md","name":"CVE-2023-30186","record":{"aliases":["GHSA-m5p8-2r8q-qjjh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ONLYOFFICE DocumentServer","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via crafted JavaScript files due to a use-after-free vulnerability in ONLYOFFICE DocumentServer.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"document_server","vendor":"onlyoffice"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use after free issue discovered in ONLYOFFICE DocumentServer 4.0.3 through 7.3.2 allows remote attackers to run arbitrary code via crafted JavaScript file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Use after free in n/a","id":"CVE-2023-30186","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-30187"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2023-30185"},"products":["n/a"],"published":"2023-08-14","related":[{"cvss_score":9.8,"headline":"ONLYOFFICE Docs Server Path Traversal","id":"CVE-2021-3199","kev_date_added":"2026-10-08","published":"2021-01-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-30187","kev_date_added":null,"published":"2023-08-14"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2021-25830","kev_date_added":null,"published":"2021-03-01"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2021-25831","kev_date_added":null,"published":"2021-03-01"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-25832","kev_date_added":null,"published":"2021-03-01"},{"cvss_score":9.8,"headline":"12345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890","id":"CVE-2021-25833","kev_date_added":null,"published":"2021-03-01"}],"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via crafted JavaScript files due to a use-after-free vulnerability in ONLYOFFICE DocumentServer.","url":"https://insights.sbomify.com/CVE-2023-30186/"}
