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. This issue is fixed in versions 1.7.4 and 1.8.1.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":null}],"references":["https://github.com/envoyproxy/gateway/security/advisories/GHSA-cxpq-8v7q-cg56","https://github.com/envoyproxy/gateway/pull/9171","https://github.com/envoyproxy/gateway/pull/9172","https://github.com/envoyproxy/gateway/pull/9173","https://github.com/envoyproxy/gateway/commit/5a78db82b7cf4fc5bebbeda2c50952892038a464","https://github.com/envoyproxy/gateway/commit/96e2b750868a459ace4b8b68e6a6e4fb0152b9b7","https://github.com/envoyproxy/gateway/commit/b4737180c7e597490c6363075c565fa8cf24eead","https://github.com/envoyproxy/gateway/releases/tag/v1.7.4","https://github.com/envoyproxy/gateway/releases/tag/v1.8.1"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-78079","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 14, 2026, 8:15:51 PM","dateUpdated":"Sep 16, 2026, 4:21:20 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
