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-2016-10520 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jadedown (npm): affected all versions up to 0.0.3; no fix listed\n- jadedown (npm): affected all versions up to 0.0.3; no fix listed\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-2016-10520/ (Markdown: https://insights.sbomify.com/CVE-2016-10520/index.md)","id":"CVE-2016-10520","markdown":"https://insights.sbomify.com/CVE-2016-10520/index.md","name":"CVE-2016-10520","record":{"aliases":["GHSA-6354-6mhv-mvv5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js markdown parser","requires_auth":"none","summary":"Attackers can cause a denial of service in the jadedown library by submitting specially crafted input that triggers excessive regular expression processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"jadedown","vendor":"jadedown_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"jadedown is vulnerable to regular expression denial of service (ReDoS) when certain types of user input is passed in.","ecosystems":["npm"],"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":"Regular Expression Denial of Service in jadedown","id":"CVE-2016-10520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2016"},"n_packages":2,"n_references":1,"next":{"headline":"Regular Expression Denial of Service in jshamcrest","id":"CVE-2016-10521"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.0.3"],"package":"jadedown","purl":null,"source":"GHSA-6354-6mhv-mvv5"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.0.3"],"package":"jadedown","purl":"pkg:npm/jadedown","source":"GHSA-6354-6mhv-mvv5"}],"prev":{"headline":"Remote Memory Disclosure in bittorrent-dht","id":"CVE-2016-10519"},"products":["jadedown node module"],"published":"2018-05-31","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-09-17","vendors":["HackerOne"]},"summary":"Attackers can cause a denial of service in the jadedown library by submitting specially crafted input that triggers excessive regular expression processing.","url":"https://insights.sbomify.com/CVE-2016-10520/"}
