CVE-2021-48011

Servor 1.0.0 through 4.0.2 contains a path traversal vulnerability that allows unauthenticated remote attackers to escape the served root by sending URL-encoded dot segments. Attackers can send %2e%2e/ sequences, which decodeURI decodes before path.join in serveStaticFile and serveDirectoryListin...

CVE-2021-48011

The Servor web server versions 1.0.0 through 4.0.2 are vulnerable to a path traversal vulnerability. The root cause lies in the serveStaticFile and serveDirectoryListing functions, where decodeURI() processes URL-encoded dot segments (such as %2e%2e/) before path.join() is executed. This allows u...

SUSE 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-2026-59731

Astro is a web framework for content-driven websites. Version 6.4.7 performs authorization decisions on a partially decoded pathname after reaching the iterative URL decoder limit, while later rewrite route matching performs an additional decodeURI operation and can resolve the request to a...

CVE-2026-59731: Use of Non-Canonical URL Paths for Authorization Decisions

CVE-2026-8162

[email protected] and lower versions are vulnerable to denial of service via uncaught exception. By sending a multipart/form-data request with a Content-Disposition header whose filename parameter contains a malformed percent-encoding, the parser invokes decodeURI on the value without try/catch. T...

CVE-2026-8162: Improper Handling of Exceptional Conditions

By sending a multipart/form-data request with a Content-Disposition header whose filename parameter contains a malformed percent-encoding, the parser invokes decodeURI on the value without try/catch. T...

PT-2026-29172

Summary The serveStatic utility in h3 applies a redundant decodeURI call to the request pathname after H3Event has already performed percent-decoding with %25 preservation. This double decoding converts %252e%252e into %2e%2e, which bypasses resolveDotSegments since it checks for literal...

PT-2026-28778

Summary serveStatic in h3 is vulnerable to path traversal via percent-encoded dot segments %2e%2e, allowing an unauthenticated attacker to read arbitrary files outside the intended static directory on Node.js deployments. Details The vulnerability exists in src/utils/static.ts at line 86:...

CVE-2026-29045 Hono: Arbitrary file access via serveStatic vulnerability

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to version 4.12.4, when using serveStatic together with route-based middleware protections e.g. app.use'/admin/', ..., inconsistent URL decoding allowed protected static resources to be accessed without...

CVE-2025-64765: Improper Limitation of a Pathname to a Restricted Directory

Astro is a web framework. Prior to version 5.15.8, a mismatch exists between how Astro normalizes request paths for routing/rendering and how the application’s middleware reads the path for validation checks. Astro internally applies decodeURI to determine which route to render, while the...
