Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53719 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/envoyproxy/gateway (Go): affected all versions; fixed in 1.7.4, 1.8.1\n- github.com/envoyproxy/gateway (Go): affected all versions; fixed in 1.7.4\n- github.com/envoyproxy/gateway (Go): affected all versions; fixed in 1.7.4\n- github.com/envoyproxy/gateway (Go): affected from 1.8.0-rc.0; fixed in 1.8.1\n- github.com/envoyproxy/gateway (Go): affected from 1.8.0-rc.0; fixed in 1.8.1\n- envoy-gateway (Bitnami): affected all versions; fixed in 1.7.4, 1.8.1\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-2026-53719/ (Markdown: https://insights.sbomify.com/CVE-2026-53719/index.md)","id":"CVE-2026-53719","markdown":"https://insights.sbomify.com/CVE-2026-53719/index.md","name":"CVE-2026-53719","record":{"aliases":["BIT-envoy-gateway-2026-53719","CLEANSTART-2026-IG75377","CLEANSTART-2026-XZ22302","GHSA-m2v6-2jmh-4c68","GO-2026-6009","MINI-6c3h-cc5c-3j9f","MINI-c4f2-5r9g-6f7h","MINI-gvv9-5w2q-5qxm","MINI-qjmg-hmxx-cxfr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Envoy Gateway","requires_auth":"low_privilege","summary":"A nil pointer dereference in Envoy Gateway causes a panic and stalls control plane updates when a SecurityPolicy targets a TCPRoute without authorization, requiring an upgrade.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. Prior to 1.7.4 and 1.8.1, translateSecurityPolicyForRoute in internal/gatewayapi/securitypolicy.go dereferences a nil authorization value when a namespace-scoped tenant creates a SecurityPolicy targeting a TCPRoute and omits spec.authorization. The persistent object triggers the panic on every reconcile; recovery in message/watchutil.go keeps the process alive but unwinds the runner/runner.go handle callback, stalling controller-wide xDS and infrastructure intermediate-representation publishing until an administrator deletes the object. The data plane continues to serve the last known good configuration while publication is stalled.
