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-2026-86253

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-2026-86251

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...

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. 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...
