Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-15738 in the wild and no public exploit code.\n\nAffected product: Amazon aws-load-balancer-controller. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-15738/ (Markdown: https://insights.sbomify.com/CVE-2026-15738/index.md)","id":"CVE-2026-15738","markdown":"https://insights.sbomify.com/CVE-2026-15738/index.md","name":"CVE-2026-15738","record":{"aliases":[],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"AWS Load Balancer Controller","requires_auth":"low_privilege","summary":"An authenticated user can intercept, spoof, or deny gRPC traffic from other namespaces by exploiting incorrect route precedence in the AWS Load Balancer Controller.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-653","name":"Improper Isolation or Compartmentalization"}],"description":"Incorrect behavior order in the Gateway API listener-rule generation in Amazon AWS Load Balancer Controller before 3.4.2 might allow an authenticated remote user to intercept, spoof, or deny another namespace's gRPC traffic on a shared Gateway via a crafted HTTPRoute resource.\n\nTo mitigate this issue, users should upgrade to version 3.4.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross-namespace traffic interception via incorrect route precedence ordering in AWS Load Balancer Controller","id":"CVE-2026-15738","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Rich Showcase for Google Reviews","id":"CVE-2026-15739"},"packages":[],"prev":{"headline":"Sensitive content disclosure via OpenTelemetry spans in AgentCore Python SDK","id":"CVE-2026-15737"},"products":["aws-load-balancer-controller"],"published":"2026-07-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-07-15","vendors":["Amazon"]},"summary":"An authenticated user can intercept, spoof, or deny gRPC traffic from other namespaces by exploiting incorrect route precedence in the AWS Load Balancer Controller.","url":"https://insights.sbomify.com/CVE-2026-15738/"}
