An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-23047 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/cilium/cilium (Go): affected from 1.14.0; fixed in 1.14.19, 1.15.13, 1.16.6\n- github.com/cilium/cilium (Go): affected from 1.14.0; fixed in 1.14.19\n- github.com/cilium/cilium (Go): affected from 1.14.0; fixed in 1.14.19\n- github.com/cilium/cilium (Go): affected from 1.15.0; fixed in 1.15.13\n- github.com/cilium/cilium (Go): affected from 1.15.0; fixed in 1.15.13\n- github.com/cilium/cilium (Go): affected from 1.16.0; fixed in 1.16.6\n- github.com/cilium/cilium (Go): affected from 1.16.0; fixed in 1.16.6\n- cilium (Bitnami): affected from 1.14.0; fixed in 1.16.5\n- cilium-operator (Bitnami): affected from 1.15.4; fixed in 1.16.5\n- hubble-relay (Bitnami): affected from 1.14.0; fixed in 1.16.5\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-2025-23047/ (Markdown: https://insights.sbomify.com/CVE-2025-23047/index.md)","id":"CVE-2025-23047","markdown":"https://insights.sbomify.com/CVE-2025-23047/index.md","name":"CVE-2025-23047","record":{"aliases":["BIT-cilium-2025-23047","BIT-cilium-operator-2025-23047","BIT-hubble-relay-2025-23047","GHSA-h78m-j95m-5356","GO-2025-3416"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cilium Hubble UI","requires_auth":"none","summary":"Insecure CORS headers in Hubble UI allow attackers to leak Kubernetes cluster configuration details if a victim visits a malicious page.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cilium","vendor":"cilium"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An insecure default `Access-Control-Allow-Origin` header value could lead to sensitive data exposure for users of Cilium versions 1.14.0 through 1.14.7, 1.15.0 through 1.15.11, and 1.16.0 through 1.16.4 who deploy Hubble UI using either Cilium CLI or via the Cilium Helm chart. A user with access to a Hubble UI instance affected by this issue could leak configuration details about the Kubernetes cluster which Hubble UI is monitoring, including node names, IP addresses, and other metadata about workloads and the cluster networking configuration. In order for this vulnerability to be exploited, a victim would have to first visit a malicious page. This issue is fixed in Cilium v1.14.18, v1.15.12, and v1.16.5. As a workaround, users who deploy Hubble UI using the Cilium Helm chart directly can remove the CORS headers from the Helm template as shown in the patch from commit a3489f190ba6e87b5336ee685fb6c80b1270d06d.","ecosystems":["Bitnami","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":"Cilium vulnerable to information leakage via insecure default Hubble UI CORS header","id":"CVE-2025-23047","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":10,"n_references":2,"next":{"headline":"Apache HTTP Server: mod_ssl access control bypass with session resumption","id":"CVE-2025-23048"},"packages":[{"ecosystem":"Bitnami","fixed":["1.16.5"],"introduced":["1.14.0"],"last_affected":[],"package":"cilium","purl":"pkg:bitnami/cilium","source":"BIT-cilium-2025-23047"},{"ecosystem":"Bitnami","fixed":["1.16.5"],"introduced":["1.15.4"],"last_affected":[],"package":"cilium-operator","purl":"pkg:bitnami/cilium-operator","source":"BIT-cilium-operator-2025-23047"},{"ecosystem":"Bitnami","fixed":["1.16.5"],"introduced":["1.14.0"],"last_affected":[],"package":"hubble-relay","purl":"pkg:bitnami/hubble-relay","source":"BIT-hubble-relay-2025-23047"},{"ecosystem":"Go","fixed":["1.14.19","1.15.13","1.16.6"],"introduced":["1.14.0","1.15.0","1.16.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GO-2025-3416"},{"ecosystem":"Go","fixed":["1.14.19"],"introduced":["1.14.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":null,"source":"GHSA-h78m-j95m-5356"},{"ecosystem":"Go","fixed":["1.14.19"],"introduced":["1.14.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GHSA-h78m-j95m-5356"},{"ecosystem":"Go","fixed":["1.15.13"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":null,"source":"GHSA-h78m-j95m-5356"},{"ecosystem":"Go","fixed":["1.15.13"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GHSA-h78m-j95m-5356"},{"ecosystem":"Go","fixed":["1.16.6"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":null,"source":"GHSA-h78m-j95m-5356"},{"ecosystem":"Go","fixed":["1.16.6"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GHSA-h78m-j95m-5356"}],"prev":{"headline":"GLPI vulnerable to unauthorized authentication by email using the OAuthIMAP plugin","id":"CVE-2025-23046"},"products":["cilium"],"published":"2025-01-22","related":[{"cvss_score":9.2,"headline":"Cilium: Sensitive information disclosure and cluster disruption via local Envoy admin socket access","id":"CVE-2026-49445","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":8.8,"headline":"Incorrect Default Permissions in Cilium","id":"CVE-2022-29178","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":8,"headline":"Insecure IPsec transport encryption in Cilium","id":"CVE-2024-28860","kev_date_added":null,"published":"2024-03-27"},{"cvss_score":7.9,"headline":"Cillium exposes sensitive information included in the cilium-bugtool debug archive","id":"CVE-2026-41520","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":7.9,"headline":"Cilium leaks sensitive information in cilium-bugtool","id":"CVE-2024-37307","kev_date_added":null,"published":"2024-06-13"},{"cvss_score":7.6,"headline":"Cilium NetworkPolicy bypass via pod labels","id":"CVE-2023-39347","kev_date_added":null,"published":"2023-09-26"},{"cvss_score":7.5,"headline":"Improper Privilege Management in Cilium","id":"CVE-2022-29179","kev_date_added":null,"published":"2022-05-20"}],"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":"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":"2025-02-12","vendors":["cilium"]},"summary":"Insecure CORS headers in Hubble UI allow attackers to leak Kubernetes cluster configuration details if a victim visits a malicious page.","url":"https://insights.sbomify.com/CVE-2025-23047/"}
