Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-44774 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 3.6.17, 3.7.1\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.6.17\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.6.17\n- github.com/traefik/traefik/v3 (Go): affected from 3.7.0; fixed in 3.7.1\n- github.com/traefik/traefik/v3 (Go): affected from 3.7.0; fixed in 3.7.1\n- github.com/traefik/traefik (Go): affected all versions; no fix listed\n- github.com/traefik/traefik (Go): affected all versions up to 1.7.34; no fix listed\n- github.com/traefik/traefik (Go): affected all versions up to 1.7.34; no fix listed\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.46\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.46\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.46\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-2026-44774/ (Markdown: https://insights.sbomify.com/CVE-2026-44774/index.md)","id":"CVE-2026-44774","markdown":"https://insights.sbomify.com/CVE-2026-44774/index.md","name":"CVE-2026-44774","record":{"aliases":["CLEANSTART-2026-PG87313","GHSA-96qj-4jj5-wcjc","GO-2026-5277","MINI-83q9-fgj2-hrmh","MINI-x259-rrhm-m8h3","MINI-xpwq-9wrg-q98c","openSUSE-SU-2026:10810-1","openSUSE-SU-2026:10811-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Traefik reverse proxy","requires_auth":"low_privilege","summary":"A low-privileged user can bypass REST provider security settings to gain unauthorized write access to Traefik's dynamic configuration.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"traefik","vendor":"traefik"}],"cvss":{"score":6.4,"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:L/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-15","name":"External Control of System or Configuration Setting"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Traefik is an HTTP reverse proxy and load balancer. Prior to 2.11.46, 3.6.17, and 3.7.1, Traefik's Kubernetes Gateway API provider allows a tenant with HTTPRoute creation permissions to expose the REST provider handler, bypassing the providers.rest.insecure=false setting. The Gateway provider accepts any TraefikService backend reference whose name ends with @internal, making it possible to route traffic to rest@internal in addition to the intended api@internal. In shared Gateway deployments where the REST provider is enabled, this allows a low-privileged actor to gain live dynamic configuration write access to Traefik, enabling unauthorized reconfiguration of routers and services. This vulnerability is fixed in 2.11.46, 3.6.17, and
