CVE-2026-18248

CVE-2026-18248 affects @fastify/aws-lambda 6.4.0, where request.awsLambda.event and request.awsLambda.context are decorated using client-controlled x-apigateway-event and x-apigateway-context headers. The getter may read untrusted headers before the internal per-invocation token, leaving reserved...

CVE-2026-18248

@fastify/aws-lambda version 6.4.0 decorates each Fastify request with request.awsLambda.event and request.awsLambda.context, values that applications are documented to use for authorization decisions such as reading API Gateway authorizer claims. In the default configuration, the getter that...

CVE-2026-15144 @fastify/rate-limit vulnerable to rate-limit bypass via IPv6 address rotation

@fastify/rate-limit before 11.2.0 keys rate-limit buckets by the verbatim client IP string returned from request.ip. Because a single IPv6 client can control a large address range a /64 holds 2^64 distinct addresses and the same address has multiple valid textual representations, an IPv6 capable...

CVE-2026-18174

@fastify/forwarded resolves client addresses from the X-Forwarded-For header. In versions before 3.0.2, when the header contains two or more comma separated entries, the parser trims only space characters and does not strip horizontal tabs, even though RFC 7230 defines optional whitespace as both...

CVE-2026-18174 @fastify/forwarded vulnerable to improper input validation via unstripped tab characters in X-Forwarded-For

@fastify/forwarded resolves client addresses from the X-Forwarded-For header. In versions before 3.0.2, when the header contains two or more comma separated entries, the parser trims only space characters and does not strip horizontal tabs, even though RFC 7230 defines optional whitespace as both...

CVE-2026-18174

The CVE-2026-18174 entry concerns @fastify/forwarded. In versions before 3.0.2, the X-Forwarded-For parser trims only spaces when entries are comma-separated and does not strip horizontal tabs. As a result, an entry padded with a tab retains a literal tab in the resolved client IP string, potenti...

GHSA-8PVW-JCV7-9CMJ @fastify/static vulnerable to Authorization Bypass via Non-Canonical URL Paths

Impact @fastify/static evaluates the allowedPath callback before normalizing dot segments and duplicate slashes in the pathname used for file resolution. Non-canonical pathnames such as //file, /./file, or /public/../private/file bypass allowedPath filtering while resolving to the intended file o...

GHSA-83W8-P2F5-377R @fastify/static vulnerable to route guard bypass via path traversal

Impact @fastify/static is vulnerable to a bypass of route-based middleware and guards via non-leading .. and %2E%2E path segments. find-my-way does not normalize .. when matching routes, so a request such as /foo/../deep/secret.txt matches the static plugin's catch-all instead of the guarded...

Directory Traversal

Overview @fastify/static is a Plugin for serving static files as fast as possible. Affected versions of this package are vulnerable to Directory Traversal through getPathnameForSend in index.js. An attacker can reach static files protected by route-based middleware or guards by sending a request...

Incorrect Behavior Order: Validate Before Canonicalize

Overview @fastify/static is a Plugin for serving static files as fast as possible. Affected versions of this package are vulnerable to Incorrect Behavior Order: Validate Before Canonicalize via non-canonical URL path handling in the allowedPath check in index.js. An attacker can bypass file/subtr...

CVE-2026-7120

@fastify/static evaluates the allowedPath callback before normalizing dot segments and duplicate path separators in the pathname used for file resolution. Versions up to and including 10.1.1 are affected. An unauthenticated attacker can bypass allowedPath restrictions by requesting equivalent...

CVE-2026-15074

@fastify/static up to and including version 10.1.0 fails to reject dot-dot path segments in request pathnames before the file-resolution stage. This is a bypass of the earlier fix for CVE-2026-6414, which only covered encoded forward slashes. Because the underlying send library normalizes dot...
