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-2026-40460 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nginx (Bitnami): affected from 1.26.0; fixed in 1.30.1\n- nginx-gateway (Bitnami): affected from 1.26.0; fixed in 1.30.1\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-2026-40460/ (Markdown: https://insights.sbomify.com/CVE-2026-40460/index.md)","id":"CVE-2026-40460","markdown":"https://insights.sbomify.com/CVE-2026-40460/index.md","name":"CVE-2026-40460","record":{"aliases":["ALPINE-CVE-2026-40460","AZL-86847","BELL-CVE-2026-40460","BIT-nginx-2026-40460","BIT-nginx-gateway-2026-40460","DEBIAN-CVE-2026-40460","ECHO-b094-3180-9b8a","GHSA-h7rq-f9gq-mc8r","MINI-43f3-x4g5-x96q","MINI-crxh-h524-c47q","MINI-cxc4-x3j4-7qmm","MINI-fhgc-2gj6-f892","MINI-frhh-rwrh-rxh9","UBUNTU-CVE-2026-40460"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"NGINX web server","requires_auth":"none","summary":"Attackers can spoof source IPs in NGINX HTTP/3 QUIC configurations to bypass authorization and rate limiting controls.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"dos","vendor":"f5"},{"product":"nginx_gateway_fabric","vendor":"f5"},{"product":"nginx_ingress_controller","vendor":"f5"},{"product":"nginx_instance_manager","vendor":"f5"},{"product":"nginx_open_source","vendor":"f5"},{"product":"nginx_plus","vendor":"f5"},{"product":"waf","vendor":"f5"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"When NGINX Plus or NGINX Open Source are configured to use the HTTP/3 QUIC module, an attacker may be able to spoof their source IP address allowing for bypass of authorization or bypass of rate limiting.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.","ecosystems":["Bitnami"],"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":"NGINX ngx_quic_module vulnerability","id":"CVE-2026-40460","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Anviz Products Missing Authentication for Critical Function","id":"CVE-2026-40461"},"packages":[{"ecosystem":"Bitnami","fixed":["1.30.1"],"introduced":["1.26.0"],"last_affected":[],"package":"nginx","purl":"pkg:bitnami/nginx","source":"BIT-nginx-2026-40460"},{"ecosystem":"Bitnami","fixed":["1.30.1"],"introduced":["1.26.0"],"last_affected":[],"package":"nginx-gateway","purl":"pkg:bitnami/nginx-gateway","source":"BIT-nginx-gateway-2026-40460"}],"prev":{"headline":"LDAP Injection in PAC4J","id":"CVE-2026-40459"},"products":["NGINX Open Source","NGINX Plus"],"published":"2026-05-13","related":[{"cvss_score":9.2,"headline":"NGINX ngx_http_proxy_v2_module and ngx_http_grpc_module vulnerability","id":"CVE-2026-42055","kev_date_added":null,"published":"2026-06-17"},{"cvss_score":9.2,"headline":"NGINX ngx_http_rewrite_module vulnerability","id":"CVE-2026-42945","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":8.3,"headline":"NGINX ngx_http_scgi_module and ngx_http_uwsgi_module vulnerability","id":"CVE-2026-42946","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":6.3,"headline":"NGINX ngx_http_charset_module vulnerability","id":"CVE-2026-48142","kev_date_added":null,"published":"2026-06-17"},{"cvss_score":6.3,"headline":"NGINX ngx_http_ssl_module vulnerability","id":"CVE-2026-40701","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":6.3,"headline":"NGINX ngx_http_charset_module vulnerability","id":"CVE-2026-42934","kev_date_added":null,"published":"2026-05-13"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-05-13","vendors":["F5"]},"summary":"Attackers can spoof source IPs in NGINX HTTP/3 QUIC configurations to bypass authorization and rate limiting controls.","url":"https://insights.sbomify.com/CVE-2026-40460/"}
