Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53716 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-2026-53716/ (Markdown: https://insights.sbomify.com/CVE-2026-53716/index.md)","id":"CVE-2026-53716","markdown":"https://insights.sbomify.com/CVE-2026-53716/index.md","name":"CVE-2026-53716","record":{"aliases":["BIT-envoy-gateway-2026-53716","CLEANSTART-2026-FY77467","CLEANSTART-2026-JF19024","GHSA-cxpq-8v7q-cg56","GO-2026-6006","MINI-7hhq-5rpw-g7fv","MINI-92cx-gpvp-68xc","MINI-gpx5-wvhx-6xrx","MINI-w9fp-2q8f-4398"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Envoy Gateway","requires_auth":"low_privilege","summary":"Attackers can cause persistent control-plane outages in Envoy Gateway by supplying malicious compressed Wasm payloads that trigger unbounded memory allocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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-789","name":"Memory Allocation with Excessive Size Value"}],"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, getFileFromGZ in internal/wasm/httpfetcher.go calls io.ReadAll on a gzip.Reader without limiting decompressed output when a tenant-controlled EnvoyExtensionPolicy.spec.wasm[].code.http.url points to a reachable compressed Wasm payload. The 256 MiB compressed-input cap does not constrain the expanded size, no operator Wasm URL allowlist exists, and the optional sha256 check occurs only after decompression, so a comparatively small gzip stream can force a multi-gigabyte allocation in the shared controller. The resulting out-of-memory termination restarts the controller, re-reconciles the persistent custom resource, and can create a persistent cross-tenant control-plane outage.
