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-2024-4067 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- micromatch (npm): affected all versions; fixed in 4.0.8\n- micromatch (npm): affected all versions; fixed in 4.0.8\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-2024-4067/ (Markdown: https://insights.sbomify.com/CVE-2024-4067/index.md)","id":"CVE-2024-4067","markdown":"https://insights.sbomify.com/CVE-2024-4067/index.md","name":"CVE-2024-4067","record":{"aliases":["AZL-43999","AZL-44454","CLEANSTART-2026-PI37875","CLSA-2026-1774830268","CLSA-2026-1776731781","DEBIAN-CVE-2024-4067","GHSA-952p-6rrq-rcjv","MINI-6r7j-c6j7-2gcc","MINI-8qp3-74pm-827j","ROOT-APP-NPM-CVE-2024-4067","UBUNTU-CVE-2024-4067","openSUSE-SU-2024:14007-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript matching library","requires_auth":"none","summary":"An attacker can cause a denial of service in applications using micromatch by submitting malicious input that triggers excessive regex backtracking.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Checkmarx","cpe":[{"product":"micromatch","vendor":"jonschlinkert"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","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-1333","name":"Inefficient Regular Expression Complexity"}],"description":"The NPM package `micromatch` prior to 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in `micromatch.braces()` in `index.js` because the pattern `.*` will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persists. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching. This issue was fixed in version 4.0.8.","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 in micromatch","id":"CVE-2024-4067","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":2,"n_references":5,"next":{"headline":"Memory Exhaustion in braces","id":"CVE-2024-4068"},"packages":[{"ecosystem":"npm","fixed":["4.0.8"],"introduced":["0"],"last_affected":[],"package":"micromatch","purl":null,"source":"GHSA-952p-6rrq-rcjv"},{"ecosystem":"npm","fixed":["4.0.8"],"introduced":["0"],"last_affected":[],"package":"micromatch","purl":"pkg:npm/micromatch","source":"GHSA-952p-6rrq-rcjv"}],"prev":{"headline":"Tenda AC8 AdvSetMacMtuWan fromAdvSetMacMtuWan stack-based overflow","id":"CVE-2024-4066"},"products":["micromatch"],"published":"2024-05-13","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-17","vendors":["micromatch"]},"summary":"An attacker can cause a denial of service in applications using micromatch by submitting malicious input that triggers excessive regex backtracking.","url":"https://insights.sbomify.com/CVE-2024-4067/"}
