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-2016-10521 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jshamcrest (npm): affected all versions up to 0.7.1; no fix listed\n- jshamcrest (npm): affected all versions up to 0.7.1; 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-2016-10521/ (Markdown: https://insights.sbomify.com/CVE-2016-10521/index.md)","id":"CVE-2016-10521","markdown":"https://insights.sbomify.com/CVE-2016-10521/index.md","name":"CVE-2016-10521","record":{"aliases":["GHSA-xj62-87pg-vcv3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript testing library","requires_auth":"none","summary":"Attackers can cause denial of service in jshamcrest by submitting malicious input to the email validator, affecting applications using this npm module.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"jshamcrest","vendor":"jshamcrest_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":"jshamcrest is vulnerable to regular expression denial of service (ReDoS) when certain types of user input is passed in to the emailAddress validator.","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 jshamcrest","id":"CVE-2016-10521","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":"Cross-site request forgery in rails_admin","id":"CVE-2016-10522"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.7.1"],"package":"jshamcrest","purl":null,"source":"GHSA-xj62-87pg-vcv3"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.7.1"],"package":"jshamcrest","purl":"pkg:npm/jshamcrest","source":"GHSA-xj62-87pg-vcv3"}],"prev":{"headline":"Regular Expression Denial of Service in jadedown","id":"CVE-2016-10520"},"products":["jshamcrest 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":"2024-09-16","vendors":["HackerOne"]},"summary":"Attackers can cause denial of service in jshamcrest by submitting malicious input to the email validator, affecting applications using this npm module.","url":"https://insights.sbomify.com/CVE-2016-10521/"}
