An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-40639 in the wild and no public exploit code.\n\nAffected product: Jflyfox Jfinal Cms. 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-2021-40639/ (Markdown: https://insights.sbomify.com/CVE-2021-40639/index.md)","id":"CVE-2021-40639","markdown":"https://insights.sbomify.com/CVE-2021-40639/index.md","name":"CVE-2021-40639","record":{"aliases":["GHSA-8m3p-xv8v-vgp2"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jfinal CMS","requires_auth":"none","summary":"Attackers can access sensitive configuration files in Jfinal CMS due to improper access control, leading to information disclosure.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jfinal_cms","vendor":"jflyfox"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"Improper access control in Jfinal CMS 5.1.0 allows attackers to access sensitive information via /classes/conf/db.properties\u0026config=filemanager.config.js.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Information disclosure in n/a","id":"CVE-2021-40639","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jflyfox:jfinal_cms","products":["jflyfox:jfinal_cms"],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-40642"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-40637"},"products":["n/a"],"published":"2021-09-15","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2024-53477","kev_date_added":null,"published":"2024-12-02"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-47503","kev_date_added":null,"published":"2023-11-28"},{"cvss_score":9.8,"headline":"Remote code execution in JFinal CMS","id":"CVE-2023-30349","kev_date_added":null,"published":"2023-04-27"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-37204","kev_date_added":null,"published":"2022-09-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-37203","kev_date_added":null,"published":"2022-09-19"},{"cvss_score":9.8,"headline":"SQL injection in jflyfox jfinal","id":"CVE-2022-37199","kev_date_added":null,"published":"2022-08-23"},{"cvss_score":9.8,"headline":"SQL injection in jflyfox jfinal","id":"CVE-2022-37223","kev_date_added":null,"published":"2022-08-23"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Attackers can access sensitive configuration files in Jfinal CMS due to improper access control, leading to information disclosure.","url":"https://insights.sbomify.com/CVE-2021-40639/"}
