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...

Luke Jackson Servør path traversal vulnerability

Luke Jackson Servo versions 1.0.0 to 4.0.2 and earlier have a path traversal vulnerability. This vulnerability arises from the fact that decodeURI is executed before path.join in serveStaticFile and serveDirectoryListing. Attackers can send URL-encoded strings to escape the root directory, making...

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...

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...
