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-2021-33587 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- css-what (npm): affected from 4.0.0; fixed in 5.0.1\n- css-what (npm): affected from 4.0.0; fixed in 5.0.1\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-2021-33587/ (Markdown: https://insights.sbomify.com/CVE-2021-33587/index.md)","id":"CVE-2021-33587","markdown":"https://insights.sbomify.com/CVE-2021-33587/index.md","name":"CVE-2021-33587","record":{"aliases":["CLSA-2026-1790414394","DEBIAN-CVE-2021-33587","GHSA-q8pj-2vqx-8ggc","ROOT-APP-NPM-CVE-2021-33587","UBUNTU-CVE-2021-33587"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js CSS parser","requires_auth":"none","summary":"An attacker can cause a denial of service by providing input that triggers quadratic time complexity in the CSS attribute parser.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"css-what","vendor":"css-what_project"},{"product":"e-series_performance_analyzer","vendor":"netapp"}],"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":[],"description":"The css-what package 4.0.0 through 5.0.0 for Node.js does not ensure that attribute parsing has Linear Time Complexity relative to the size of the input.","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":"Denial of service in css-what","id":"CVE-2021-33587","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"netapp:e-series_performance_analyzer","products":["netapp:e-series_performance_analyzer"],"type":"denial_of_service","year":"2021"},"n_packages":2,"n_references":3,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2021-33589"},"packages":[{"ecosystem":"npm","fixed":["5.0.1"],"introduced":["4.0.0"],"last_affected":[],"package":"css-what","purl":null,"source":"GHSA-q8pj-2vqx-8ggc"},{"ecosystem":"npm","fixed":["5.0.1"],"introduced":["4.0.0"],"last_affected":[],"package":"css-what","purl":"pkg:npm/css-what","source":"GHSA-q8pj-2vqx-8ggc"}],"prev":{"headline":"Use after free in n/a","id":"CVE-2021-33586"},"products":["n/a"],"published":"2021-05-28","related":[{"cvss_score":5.3,"headline":"Regular Expression Denial of Service (ReDoS)","id":"CVE-2022-21222","kev_date_added":null,"published":"2022-09-30"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"An attacker can cause a denial of service by providing input that triggers quadratic time complexity in the CSS attribute parser.","url":"https://insights.sbomify.com/CVE-2021-33587/"}
