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-2022-21195 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- url-regex (PyPI): affected all versions up to 1.0.4; no fix listed\n- url_regex (PyPI): affected all versions up to 1.0.4; 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-2022-21195/ (Markdown: https://insights.sbomify.com/CVE-2022-21195/index.md)","id":"CVE-2022-21195","markdown":"https://insights.sbomify.com/CVE-2022-21195/index.md","name":"CVE-2022-21195","record":{"aliases":["GHSA-hg3w-7hj9-m3f7"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python URL regex library","requires_auth":"none","summary":"Attackers can cause CPU exhaustion and service crashes in applications using the url-regex library via crafted input.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"url-regex","vendor":"url-regex_project"}],"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":"All versions of package url-regex are vulnerable to Regular Expression Denial of Service (ReDoS) which can cause the CPU usage to crash.","ecosystems":["PyPI"],"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 (ReDoS)","id":"CVE-2022-21195","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":2,"n_references":2,"next":{"headline":"Airspan Networks Mimosa Improper Authorization","id":"CVE-2022-21196"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.0.4"],"package":"url-regex","purl":"pkg:pypi/url-regex","source":"GHSA-hg3w-7hj9-m3f7"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.0.4"],"package":"url_regex","purl":null,"source":"GHSA-hg3w-7hj9-m3f7"}],"prev":{"headline":"Hardcoded credentials in CENTUM VP","id":"CVE-2022-21194"},"products":["url-regex"],"published":"2022-05-20","related":[{"cvss_score":7.5,"headline":"Regular expression denial of service in url-regex","id":"CVE-2020-7661","kev_date_added":null,"published":"2020-06-04"}],"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":["n/a"]},"summary":"Attackers can cause CPU exhaustion and service crashes in applications using the url-regex library via crafted input.","url":"https://insights.sbomify.com/CVE-2022-21195/"}
