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-2021-3794 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @vuelidate/validators (npm): affected all versions; fixed in 2.0.0-alpha.22\n- @vuelidate/validators (npm): affected all versions; fixed in 2.0.0-alpha.22\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-2021-3794/ (Markdown: https://insights.sbomify.com/CVE-2021-3794/index.md)","id":"CVE-2021-3794","markdown":"https://insights.sbomify.com/CVE-2021-3794/index.md","name":"CVE-2021-3794","record":{"aliases":["GHSA-vvf2-ppj9-pp49"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Vue validation library","requires_auth":"none","summary":"Attackers can cause denial of service in applications using vuelidate by triggering inefficient regular expression complexity.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"vuelidate","vendor":"vuelidate_project"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"vuelidate is vulnerable to Inefficient Regular Expression Complexity","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":true,"headline":"Inefficient Regular Expression Complexity in vuelidate/vuelidate","id":"CVE-2021-3794","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Inefficient Regular Expression Complexity in sindresorhus/semver-regex","id":"CVE-2021-3795"},"packages":[{"ecosystem":"npm","fixed":["2.0.0-alpha.22"],"introduced":["0"],"last_affected":[],"package":"@vuelidate/validators","purl":null,"source":"GHSA-vvf2-ppj9-pp49"},{"ecosystem":"npm","fixed":["2.0.0-alpha.22"],"introduced":["0"],"last_affected":[],"package":"@vuelidate/validators","purl":"pkg:npm/%40vuelidate/validators","source":"GHSA-vvf2-ppj9-pp49"}],"prev":{"headline":"Missing authorization in Binatone Hubble Cameras","id":"CVE-2021-3793"},"products":["vuelidate/vuelidate"],"published":"2021-09-15","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":"2024-08-03","vendors":["vuelidate"]},"summary":"Attackers can cause denial of service in applications using vuelidate by triggering inefficient regular expression complexity.","url":"https://insights.sbomify.com/CVE-2021-3794/"}
