CVE-2024-38063

CVE-2024-38063 - SSP H3 对于这个设置（来自视频的那个），我使用了 Windows 22H2 19045 和 build 2468。（这个 CVE 直到 4780 才被修补） 我在 Qemu/KVM 上尝试过，但网卡没有合并数据包（根据我用 tcpdump 调查的结果）。解决方案是使用 VirtualBox 的 Host-Only 网络。 我尝试了几个 PoC（巧干而非蛮干）： https://github.com/ThemeHackers/CVE-2024-38063...

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...

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-2026-86252

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...

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-2026-86251 h3 before 1.15.9 Path Traversal via Double Decoding

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility.

CVE-2026-86251

Versions of h3 before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. The root cause is a double-decoding flaw : a request path containing double-encoded dot sequences (e.g. %252e%252e) decodes to %2e%2e, which survives the resolveDotSegments() function because it only c...

EUVD-2026-72106

CVE-2026-86250

h3 versions before 2.0.1-rc.18 contain a denial-of-service vulnerability in the setChunkedCookie() and deleteChunkedCookie() functions. The library fails to validate the chunk count parsed from user-controlled cookie values, allowing a remote, unauthenticated attacker to send a crafted cookie hea...
