Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-4886 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- k8s.io/ingress-nginx (Go): affected all versions; fixed in 1.8.0\n- k8s.io/ingress-nginx (Go): affected all versions; fixed in 1.8.0\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-2022-4886/ (Markdown: https://insights.sbomify.com/CVE-2022-4886/index.md)","id":"CVE-2022-4886","markdown":"https://insights.sbomify.com/CVE-2022-4886/index.md","name":"CVE-2022-4886","record":{"aliases":["GHSA-gvrm-w2f9-f77q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Kubernetes ingress controller","requires_auth":"low_privilege","summary":"Attackers can bypass path sanitization in ingress-nginx using the log_format directive, potentially leading to security bypasses.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"kubernetes","cpe":[{"product":"ingress-nginx","vendor":"kubernetes"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Ingress-nginx `path` sanitization can be bypassed with `log_format` directive.","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":"Ingress-nginx `path` sanitization can be bypassed with `log_format` directive","id":"CVE-2022-4886","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"other","year":"2022"},"n_packages":2,"n_references":4,"next":{"headline":"Multiple Plugins from Addify - Multiple CSRF","id":"CVE-2022-4888"},"packages":[{"ecosystem":"Go","fixed":["1.8.0"],"introduced":["0"],"last_affected":[],"package":"k8s.io/ingress-nginx","purl":null,"source":"GHSA-gvrm-w2f9-f77q"},{"ecosystem":"Go","fixed":["1.8.0"],"introduced":["0"],"last_affected":[],"package":"k8s.io/ingress-nginx","purl":"pkg:golang/k8s.io/ingress-nginx","source":"GHSA-gvrm-w2f9-f77q"}],"prev":{"headline":"sviehb jefferson path traversal","id":"CVE-2022-4885"},"products":["ingress-nginx"],"published":"2023-10-25","related":[{"cvss_score":8.8,"headline":"ingress-nginx rewrite-target nginx configuration injection","id":"CVE-2026-3288","kev_date_added":null,"published":"2026-03-09"},{"cvss_score":7.6,"headline":"Ingress nginx annotation injection causes arbitrary command execution","id":"CVE-2023-5043","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":7.6,"headline":"Code injection via nginx.ingress.kubernetes.io/permanent-redirect annotation","id":"CVE-2023-5044","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":7.6,"headline":"Ingress-nginx `path` sanitization can be bypassed with newline character","id":"CVE-2021-25748","kev_date_added":null,"published":"2023-05-24"},{"cvss_score":7.6,"headline":"Ingress-nginx path can be pointed to service account token file","id":"CVE-2021-25745","kev_date_added":null,"published":"2022-05-06"},{"cvss_score":7.6,"headline":"Ingress-nginx directive injection via annotations","id":"CVE-2021-25746","kev_date_added":null,"published":"2022-05-06"}],"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":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Kubernetes"]},"summary":"Attackers can bypass path sanitization in ingress-nginx using the log_format directive, potentially leading to security bypasses.","url":"https://insights.sbomify.com/CVE-2022-4886/"}
