Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-32695 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.6.11, 3.7.0-ea.2\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.6.11\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.6.11\n- github.com/traefik/traefik/v3 (Go): affected from 3.7.0-ea.1; fixed in 3.7.0-ea.2\n- github.com/traefik/traefik/v3 (Go): affected from 3.7.0-ea.1; fixed in 3.7.0-ea.2\n- github.com/traefik/traefik (Go): affected all versions; no fix listed\n- github.com/traefik/traefik/v2 (Go): affected all versions; no fix listed\n- github.com/traefik/traefik/v2 (Go): affected all versions up to 2.11.42; no fix listed\n- github.com/traefik/traefik/v2 (Go): affected all versions up to 2.11.42; 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-2026-32695/ (Markdown: https://insights.sbomify.com/CVE-2026-32695/index.md)","id":"CVE-2026-32695","markdown":"https://insights.sbomify.com/CVE-2026-32695/index.md","name":"CVE-2026-32695","record":{"aliases":["ECHO-8b5a-8e18-7ee1","GHSA-67jx-r9pv-98rj","GO-2026-4880","MINI-439x-vfxf-9hpw","MINI-5jj8-r99g-fhwr","MINI-qf35-mgf8-5m2q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Traefik reverse proxy","requires_auth":"low_privilege","summary":"Traefik's Knative provider allows rule injection via unescaped host values, enabling host restriction bypass and cross-tenant traffic exposure in multi-tenant clusters.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"traefik","vendor":"traefik"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-917","name":"Improper Neutralization of Special Elements used in an Expression Language Statement"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Traefik is an HTTP reverse proxy and load balancer. Prior to versions 3.6.11 and 3.7.0-ea.2, Traefik's Knative provider builds router rules by interpolating user-controlled values into backtick-delimited rule expressions without escaping. In live cluster validation, Knative `rules[].hosts[]` was exploitable for host restriction bypass (for example `tenant.example.com`) || Host(`attacker.com`), producing a router that serves attacker-controlled hosts. Knative `headers[].exact` also allows rule-syntax injection and proves unsafe rule construction. In multi-tenant clusters, this can route unauthorized traffic to victim services and lead to cross-tenant traffic exposure. Versions 3.6.11 and 3.7.0-ea.2 patch the issue.","ecosystems":["Go"],"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":"Traefik has Knative Ingress Rule Injection that Allows Host Restriction Bypass","id":"CVE-2026-32695","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"traefik:traefik","products":["traefik:traefik"],"type":"code_injection","year":"2026"},"n_packages":9,"n_references":3,"next":{"headline":"Null dereference in nanomq","id":"CVE-2026-32696"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","source":"GO-2026-4880"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","source":"GO-2026-4880"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.11.42"],"package":"github.com/traefik/traefik/v2","purl":null,"source":"GHSA-67jx-r9pv-98rj"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.11.42"],"package":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","source":"GHSA-67jx-r9pv-98rj"},{"ecosystem":"Go","fixed":["3.6.11","3.7.0-ea.2"],"introduced":["0","3.7.0-ea.1"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GO-2026-4880"},{"ecosystem":"Go","fixed":["3.6.11"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":null,"source":"GHSA-67jx-r9pv-98rj"},{"ecosystem":"Go","fixed":["3.6.11"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GHSA-67jx-r9pv-98rj"},{"ecosystem":"Go","fixed":["3.7.0-ea.2"],"introduced":["3.7.0-ea.1"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":null,"source":"GHSA-67jx-r9pv-98rj"},{"ecosystem":"Go","fixed":["3.7.0-ea.2"],"introduced":["3.7.0-ea.1"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GHSA-67jx-r9pv-98rj"}],"prev":{"headline":"Insecure Direct Object Reference attack via predictable secret ID in Juju","id":"CVE-2026-32694"},"products":["traefik"],"published":"2026-03-27","related":[{"cvss_score":9.8,"headline":"HTTP client can remove the X-Forwarded headers in Traefik","id":"CVE-2024-45410","kev_date_added":null,"published":"2024-09-19"},{"cvss_score":9.3,"headline":"Traefik v3.7.0 Authentication Bypass via from-to-www-redirect","id":"CVE-2026-88877","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":9.3,"headline":"Traefik before v2.11.55 and v3.0.0 through v3.7.10 Authentication Bypass via digestAuth","id":"CVE-2026-85595","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":9.1,"headline":"Traefik HTTP/3 Backend NTLM Connection Reuse","id":"CVE-2026-88007","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.8,"headline":"Traefik: Rootless HTTP/1 request-target routes as \"/\" but is forwarded verbatim, bypassing path-scoped routing, middleware guards and access logging","id":"CVE-2026-88009","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.8,"headline":"Traefik has a possible vulnerability with the path matchers","id":"CVE-2025-32431","kev_date_added":null,"published":"2025-04-21"},{"cvss_score":8.2,"headline":"Traefik v3.7 Authentication Bypass via TLS Option Conflict","id":"CVE-2026-85596","kev_date_added":null,"published":"2026-09-04"}],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2026-07-15","vendors":["traefik"]},"summary":"Traefik's Knative provider allows rule injection via unescaped host values, enabling host restriction bypass and cross-tenant traffic exposure in multi-tenant clusters.","url":"https://insights.sbomify.com/CVE-2026-32695/"}
