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-2024-42486 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/cilium/cilium (Go): affected from 1.15.0; fixed in 1.15.8, 1.16.1\n- github.com/cilium/cilium (Go): affected from 1.15.0; fixed in 1.15.8\n- github.com/cilium/cilium (Go): affected from 1.15.0; fixed in 1.15.8\n- github.com/cilium/cilium (Go): affected from 1.16.0; fixed in 1.16.1\n- github.com/cilium/cilium (Go): affected from 1.16.0; fixed in 1.16.1\n- cilium (Bitnami): affected from 1.15.0; fixed in 1.16.1\n- cilium-operator (Bitnami): affected from 1.15.4; fixed in 1.16.1\n- hubble-relay (Bitnami): affected from 1.15.0; fixed in 1.16.1\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-2024-42486/ (Markdown: https://insights.sbomify.com/CVE-2024-42486/index.md)","id":"CVE-2024-42486","markdown":"https://insights.sbomify.com/CVE-2024-42486/index.md","name":"CVE-2024-42486","record":{"aliases":["BIT-cilium-2024-42486","BIT-cilium-operator-2024-42486","BIT-hubble-relay-2024-42486","GHSA-vwf8-q6fw-4wcm","GO-2024-3074"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cilium networking","requires_auth":"none","summary":"Attackers can access secrets or forward traffic across namespaces due to incorrect ReferenceGrant propagation in Cilium's Gateway API controller.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cilium","vendor":"cilium"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/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. In versions on the 1.15.x branch prior to 1.15.8 and the 1.16.x branch prior to 1.16.1, ReferenceGrant changes are not correctly propagated in Cilium's GatewayAPI controller, which could lead to Gateway resources being able to access secrets for longer than intended, or to Routes having the ability to forward traffic to backends in other namespaces for longer than intended. This issue has been patched in Cilium v1.15.8 and v1.16.1. As a workaround, any modification of a related Gateway/HTTPRoute/GRPCRoute/TCPRoute CRD (for example, adding any label to any of these resources) will trigger a reconciliation of ReferenceGrants on an affected cluster.","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 incorrect ReferenceGrant update logic in Gateway API","id":"CVE-2024-42486","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"information_disclosure","year":"2024"},"n_packages":8,"n_references":3,"next":{"headline":"Cilium's Gateway API route matching order contradicts specification","id":"CVE-2024-42487"},"packages":[{"ecosystem":"Bitnami","fixed":["1.16.1"],"introduced":["1.15.0"],"last_affected":[],"package":"cilium","purl":"pkg:bitnami/cilium","source":"BIT-cilium-2024-42486"},{"ecosystem":"Bitnami","fixed":["1.16.1"],"introduced":["1.15.4"],"last_affected":[],"package":"cilium-operator","purl":"pkg:bitnami/cilium-operator","source":"BIT-cilium-operator-2024-42486"},{"ecosystem":"Bitnami","fixed":["1.16.1"],"introduced":["1.15.0"],"last_affected":[],"package":"hubble-relay","purl":"pkg:bitnami/hubble-relay","source":"BIT-hubble-relay-2024-42486"},{"ecosystem":"Go","fixed":["1.15.8","1.16.1"],"introduced":["1.15.0","1.16.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GO-2024-3074"},{"ecosystem":"Go","fixed":["1.15.8"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":null,"source":"GHSA-vwf8-q6fw-4wcm"},{"ecosystem":"Go","fixed":["1.15.8"],"introduced":["1.15.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GHSA-vwf8-q6fw-4wcm"},{"ecosystem":"Go","fixed":["1.16.1"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":null,"source":"GHSA-vwf8-q6fw-4wcm"},{"ecosystem":"Go","fixed":["1.16.1"],"introduced":["1.16.0"],"last_affected":[],"package":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","source":"GHSA-vwf8-q6fw-4wcm"}],"prev":{"headline":"Filament Excel Vulnerable to Path Traversal Attack on Export Download Endpoint","id":"CVE-2024-42485"},"products":["cilium"],"published":"2024-08-16","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":"2024-08-16","vendors":["cilium"]},"summary":"Attackers can access secrets or forward traffic across namespaces due to incorrect ReferenceGrant propagation in Cilium's Gateway API controller.","url":"https://insights.sbomify.com/CVE-2024-42486/"}
