CVE-2026-118260：Echo BodyDump 允許無限制記錄請求與回應，導致記憶體耗盡
CVE-2026-118260 - Echo: BodyDump captures request and response bodies without size limits in v4
Echo Go Web 框架的 BodyDump 中介軟體在 v4.0.0 至 4.16.1 期間未限制請求與回應大小，易造成記憶體耗盡。
- 漏洞影響：未授權客戶可提交大請求或影響大回應，導致重複或併發分配耗盡記憶體。
此漏洞可導致記憶體耗盡，若不升級或停用 BodyDump，可能造成服務中斷或拒絕服務，建議即時升級至 4.16.1 或停用 BodyDump 以降低風險，並採取外部請求大小限制以進一步降低風險。
Echo is a Go web framework. From 4.0.0 until 4.16.1, Echo v4's opt-in BodyDump middleware reads complete request bodies into memory before handlers run and retains complete response bodies for the dump callback without capture limits. An unauthenticated client that can reach a route using BodyDump can submit large bodies or influence large responses, causing repeated or concurrent allocations that exhaust process memory. BodyDump is not enabled by default, and external request limits may reduce request-side exposure but do not bound response capture. This issue is fixed in 4.16.1.
