CVE-2024-38063

CVE-2024-38063 - SSP H3 このセットアップ（動画のもの）では、Windows 22H2 19045 とビルド 2468 を使用しました。（このCVEは4780までパッチが適用されていません） 私は Qemu/KVM でも試しましたが、ネットワークアダプタがパケットを合体（コアレッシング）しませんでした（tcpdump で調査した限りでは）。解決策は VirtualBox の Host-Only ネットワークを使用することでした。 いくつかの PoC を試しました（賢く、無理せずに）:...

CVE-2026-86205

A flaw was found in h3. This open redirect vulnerability exists in the redirectBack utility, which fails to properly sanitize protocol-relative paths in the Referer header. A remote attacker can craft a specially designed URL that bypasses origin validation, leading to a redirect to an external,...

CVE-2026-86252

A flaw was found in h3. This vulnerability allows a remote attacker to inject arbitrary Server-Sent Events SSE by failing to sanitize carriage return characters in EventStream data and comment fields. Attackers can manipulate event type directives, split single push calls into multiple...

CVE-2026-86253

A flaw was found in h3, an npm package. An unauthenticated remote attacker can exploit this vulnerability by sending crafted requests to endpoints served by the serveStatic function. On Node.js deployments, the event.url.pathname is not properly normalized, allowing percent-encoded dot segments t...

CVE-2026-86251

A flaw was found in h3. A remote attacker could exploit a path traversal vulnerability in the serveStatic utility. This vulnerability arises from a double-decoding flaw, where specially crafted, double-encoded dot sequences in a request path are incorrectly processed. This allows an attacker to...

CVE-2026-86250

A flaw was found in h3. This vulnerability allows a remote attacker to send a specially crafted cookie header with an excessively large chunk count. This action triggers an inefficient cleanup process within the setChunkedCookie and deleteChunkedCookie functions, consuming significant server...

CVE-2026-86252

h3 versions before 1.15.9 fail to sanitize carriage return characters in EventStream data and comment fields, allowing attackers to inject arbitrary SSE events by including unsanitized carriage returns. Attackers can inject event type directives, split single push calls into multiple browser-pars...

CVE-2026-86253

h3 npm package versions = 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic. On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments %2e%2e are passed to decodeURI and decoded to ../ sequences without sanitization. An unauthenticated remote...

CVE-2026-86205

h3 versions before 2.0.1-rc.18 contain an open redirect vulnerability in the redirectBack utility that fails to sanitize protocol-relative paths in the Referer header pathname. Attackers can craft a same-origin URL with a double-slash path segment that passes origin validation but produces a...

CVE-2026-86251

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences e.g. %252e%252e to be decoded to %2e%2e, which survives resolveDotSegments because that function only checks for litera...

CVE-2026-86250

h3 versions before 2.0.1-rc.18 fail to validate the chunk count parsed from user-controlled cookie values in setChunkedCookie and deleteChunkedCookie functions. Attackers can send a crafted cookie header with an extremely large chunk count to trigger an On² cleanup loop that hangs the server...

CVE-2026-86253

h3 (npm package) versions up to 2.0.1-rc.14 and 1.x before 1.15.6 are affected by a path traversal vulnerability in serveStatic() . On Node.js deployments, the URL pathname is not normalized before being passed to decodeURI(), so percent-encoded dot segments (%2e%2e) decode to ../ sequences witho...

EUVD-2026-72109

h3 npm package versions = 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic. On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments %2e%2e are passed to decodeURI and decoded to ../ sequences without sanitization. An unauthenticated remote...

CVE-2026-86253 h3 before 1.15.6 Path Traversal via Percent-Encoded Dot Segments

h3 npm package versions = 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic. On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments %2e%2e are passed to decodeURI and decoded to ../ sequences without sanitization. An unauthenticated remote...

CVE-2026-86253 h3 before 1.15.6 Path Traversal via Percent-Encoded Dot Segments

CVE-2026-86252 h3 before 1.15.9 SSE Event Injection via Carriage Return

h3 versions before 1.15.9 fail to sanitize carriage return characters in EventStream data and comment fields, allowing attackers to inject arbitrary SSE events by including unsanitized carriage returns. Attackers can inject event type directives, split single push calls into multiple browser-pars...

CVE-2026-86252

h3 versions before 1.15.9 fail to sanitize carriage return characters in EventStream data and comment fields, enabling attackers to inject arbitrary SSE events . The flaw allows injection of event type directives, splitting a single push call into multiple browser-parsed events, or escaping comme...
