It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-42371 in the wild and no public exploit code.\n\nAffected product: uriparser. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-42371/ (Markdown: https://insights.sbomify.com/CVE-2026-42371/index.md)","id":"CVE-2026-42371","markdown":"https://insights.sbomify.com/CVE-2026-42371/index.md","name":"CVE-2026-42371","record":{"aliases":["AZL-84396","DEBIAN-CVE-2026-42371","ECHO-3740-13e8-652e","GHSA-3f6w-rmcx-pgmh","RHSA-2026:12430","ROOT-OS-DEBIAN-12-CVE-2026-42371","UBUNTU-CVE-2026-42371"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"URI parsing library","requires_auth":"none","summary":"Attackers can cause denial of service by submitting extremely large URIs, triggering numeric truncation in the uriparser library.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"uriparser","vendor":"uriparser_project"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-197","name":"Numeric Truncation Error"}],"description":"uriparser before 1.0.1 has numeric truncation in text range comparison, if an application accepts URIs with a length in gigabytes.","ecosystems":["Red Hat:hummingbird:1"],"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":"Integer overflow in uriparser","id":"CVE-2026-42371","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":5,"n_references":2,"next":{"headline":"D-Link DIR-605L A1 Hardcoded Telnet Backdoor Credentials","id":"CVE-2026-42372"},"packages":[{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.0.1-1.hum1"],"introduced":["0"],"last_affected":[],"package":"mingw32-uriparser","purl":"pkg:rpm/redhat/mingw32-uriparser","source":"RHSA-2026:12430"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.0.1-1.hum1"],"introduced":["0"],"last_affected":[],"package":"mingw64-uriparser","purl":"pkg:rpm/redhat/mingw64-uriparser","source":"RHSA-2026:12430"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.0.1-1.hum1"],"introduced":["0"],"last_affected":[],"package":"uriparser","purl":"pkg:rpm/redhat/uriparser","source":"RHSA-2026:12430"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.0.1-1.hum1"],"introduced":["0"],"last_affected":[],"package":"uriparser-devel","purl":"pkg:rpm/redhat/uriparser-devel","source":"RHSA-2026:12430"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.0.1-1.hum1"],"introduced":["0"],"last_affected":[],"package":"uriparser-doc","purl":"pkg:rpm/redhat/uriparser-doc","source":"RHSA-2026:12430"}],"prev":{"headline":"GeoVision GV-VMS V20 WebCam Server Login stack overflow vulnerability","id":"CVE-2026-42370"},"products":["uriparser"],"published":"2026-04-27","related":[{"cvss_score":2.9,"headline":"Integer overflow in uriparser","id":"CVE-2026-44927","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":2.9,"headline":"Other in uriparser","id":"CVE-2026-44928","kev_date_added":null,"published":"2026-05-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-27","vendors":["uriparser"]},"summary":"Attackers can cause denial of service by submitting extremely large URIs, triggering numeric truncation in the uriparser library.","url":"https://insights.sbomify.com/CVE-2026-42371/"}
