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-2026-73547 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- envoy (Bitnami): affected all versions; fixed in 1.36.10, 1.37.6, 1.38.4, 1.39.1\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-2026-73547/ (Markdown: https://insights.sbomify.com/CVE-2026-73547/index.md)","id":"CVE-2026-73547","markdown":"https://insights.sbomify.com/CVE-2026-73547/index.md","name":"CVE-2026-73547","record":{"aliases":["BIT-envoy-2026-73547","GHSA-87ph-jqwm-pg6r","MINI-444v-2hmv-7rvm","MINI-cp2r-m2gm-cjx6","MINI-f4r5-8mv9-wrwp","MINI-hvc9-x86w-85fr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Envoy proxy","requires_auth":"none","summary":"An unauthenticated attacker can crash the Envoy proxy by sending a path-less CONNECT request when ext_authz query-parameter mutation is configured.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"envoy","vendor":"envoyproxy"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's ext_authz filter assumes that a request contains a :path pseudoheader when applying query_parameters_to_set or query_parameters_to_remove from an authorization response. A path-less CONNECT request makes request_headers_-\u003ePath() return null, and Filter::onComplete dereferences that pointer while parsing the query string. An unauthenticated downstream client can crash the Envoy process when the filter and authorization response use query-parameter mutation. The relevant scope boundary is that the deployment must accept path-less CONNECT and configure ext_authz query-parameter mutation. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.","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":"Envoy ext_authz: request `:path` pseudoheader dereferenced w/o null check","id":"CVE-2026-73547","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"envoyproxy:envoy","products":["envoyproxy:envoy"],"type":"null_dereference","year":"2026"},"n_packages":1,"n_references":9,"next":{"headline":"Envoy: Cross-user response poisoning via a generic (non-WebSocket) HTTP upgrade on Envoy's shared backend pool","id":"CVE-2026-73548"},"packages":[{"ecosystem":"Bitnami","fixed":["1.36.10","1.37.6","1.38.4","1.39.1"],"introduced":["0","1.37.0","1.38.0","1.39.0"],"last_affected":[],"package":"envoy","purl":"pkg:bitnami/envoy","source":"BIT-envoy-2026-73547"}],"prev":{"headline":"Envoy: Stored XSS in Admin Stats Interface (/stats?format=html)","id":"CVE-2026-73546"},"products":["envoy"],"published":"2026-09-21","related":[{"cvss_score":10,"headline":"Trivial authentication bypass in Envoy","id":"CVE-2022-29226","kev_date_added":null,"published":"2022-06-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-18801","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2019-18802","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":8.8,"headline":"Information disclosure in n/a","id":"CVE-2020-35470","kev_date_added":null,"published":"2020-12-15"},{"cvss_score":8.6,"headline":"Envoy ext auth can be bypassed when Proxy protocol filter sets invalid UTF-8 metadata","id":"CVE-2024-23324","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":8.6,"headline":"Envoy vulnerable to OAuth2 credentials exploit with permanent validity","id":"CVE-2023-35941","kev_date_added":null,"published":"2023-07-25"},{"cvss_score":8.6,"headline":"Incorrect handling of H2 GOAWAY + SETTINGS frames","id":"CVE-2021-39162","kev_date_added":null,"published":"2021-09-09"}],"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":"2026-09-22","vendors":["envoyproxy"]},"summary":"An unauthenticated attacker can crash the Envoy proxy by sending a path-less CONNECT request when ext_authz query-parameter mutation is configured.","url":"https://insights.sbomify.com/CVE-2026-73547/"}
