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-2021-29060 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- color-string (npm): affected all versions; fixed in 1.5.5\n- color-string (npm): affected all versions; fixed in 1.5.5\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-2021-29060/ (Markdown: https://insights.sbomify.com/CVE-2021-29060/index.md)","id":"CVE-2021-29060","markdown":"https://insights.sbomify.com/CVE-2021-29060/index.md","name":"CVE-2021-29060","record":{"aliases":["CLSA-2026-1774570927","DEBIAN-CVE-2021-29060","GHSA-257v-vj4p-3w2h","UBUNTU-CVE-2021-29060"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript color library","requires_auth":"none","summary":"Attackers can cause a denial of service in applications using the Color-String library by providing crafted invalid HWB strings that trigger excessive CPU usage.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"color-string","vendor":"color-string_project"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A Regular Expression Denial of Service (ReDOS) vulnerability was discovered in Color-String version 1.5.5 and below which occurs when the application is provided and checks a crafted invalid HWB string.","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":"Regular Expression Denial of Service (ReDOS)","id":"CVE-2021-29060","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":2,"n_references":4,"next":{"headline":"ReDOS in Vfsjfilechooser2","id":"CVE-2021-29061"},"packages":[{"ecosystem":"npm","fixed":["1.5.5"],"introduced":["0"],"last_affected":[],"package":"color-string","purl":null,"source":"GHSA-257v-vj4p-3w2h"},{"ecosystem":"npm","fixed":["1.5.5"],"introduced":["0"],"last_affected":[],"package":"color-string","purl":"pkg:npm/color-string","source":"GHSA-257v-vj4p-3w2h"}],"prev":{"headline":"ReDOS in IS-SVG","id":"CVE-2021-29059"},"products":["n/a"],"published":"2021-06-21","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":["n/a"]},"summary":"Attackers can cause a denial of service in applications using the Color-String library by providing crafted invalid HWB strings that trigger excessive CPU usage.","url":"https://insights.sbomify.com/CVE-2021-29060/"}
