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-2026-49234 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- routinator (crates.io): affected all versions; fixed in 0.15.2\n- routinator (crates.io): affected all versions; fixed in 0.15.2\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-2026-49234/ (Markdown: https://insights.sbomify.com/CVE-2026-49234/index.md)","id":"CVE-2026-49234","markdown":"https://insights.sbomify.com/CVE-2026-49234/index.md","name":"CVE-2026-49234","record":{"aliases":["GHSA-gc6q-cwcj-3vh9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"RPKI validation server","requires_auth":"none","summary":"Attackers can crash the Routinator RPKI server by sending malformed ASN strings to the API, affecting deployments with open API access.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NLnet Labs","cpe":[{"product":"routinator","vendor":"nlnetlabs"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"When sending a specifically crafted non-UTF-8 string as select-asn query parameter to the /api/v1/origins endpoint, Routinator crashes. \n\nThis only affects users who allow API access from untrusted networks.","ecosystems":["crates.io"],"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":"Routinator crashes on specifically crafted ASN strings in the API","id":"CVE-2026-49234","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Routinator crashes on specifically crafted RRDP XML files","id":"CVE-2026-49235"},"packages":[{"ecosystem":"crates.io","fixed":["0.15.2"],"introduced":["0"],"last_affected":[],"package":"routinator","purl":null,"source":"GHSA-gc6q-cwcj-3vh9"},{"ecosystem":"crates.io","fixed":["0.15.2"],"introduced":["0"],"last_affected":[],"package":"routinator","purl":"pkg:cargo/routinator","source":"GHSA-gc6q-cwcj-3vh9"}],"prev":{"headline":"Routinator cache path traversal using rogue rsync URIs","id":"CVE-2026-49233"},"products":["Routinator"],"published":"2026-06-08","related":[{"cvss_score":9.3,"headline":"Possible path traversal when storing RRDP responses","id":"CVE-2023-39916","kev_date_added":null,"published":"2023-09-13"},{"cvss_score":8.7,"headline":"Routinator crashes on specifically crafted RRDP XML files","id":"CVE-2026-49235","kev_date_added":null,"published":"2026-06-08"},{"cvss_score":8.3,"headline":"Routinator cache path traversal using rogue rsync URIs","id":"CVE-2026-49233","kev_date_added":null,"published":"2026-06-08"},{"cvss_score":7.5,"headline":"Crashes on parsing certain invalid RPKI objects","id":"CVE-2023-39915","kev_date_added":null,"published":"2023-09-13"},{"cvss_score":7.5,"headline":"Fatal error on incorrect base64 data in RRDP","id":"CVE-2022-3029","kev_date_added":null,"published":"2022-09-13"},{"cvss_score":7.5,"headline":"Infinite length chain of RRDP repositories","id":"CVE-2021-43172","kev_date_added":null,"published":"2021-11-09"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-08","vendors":["NLnet Labs"]},"summary":"Attackers can crash the Routinator RPKI server by sending malformed ASN strings to the API, affecting deployments with open API access.","url":"https://insights.sbomify.com/CVE-2026-49234/"}
