CVE-2021-48011 Servor 1.0.0 through 4.0.2 Unauthenticated Path Traversal via URL-Encoded Dot Segments

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...

Contao: Path traversal in the images controller

ImagesController joins the user controlled path onto the configured image target directory with Path::join, which canonicalises .. segments, and never calls Path::isBasePath to confirm the result stayed inside that directory. An unauthenticated GET with percent encoded dot segments therefore...

BIT-KYVERNO-2026-100707 Kyverno before 1.19.1 Namespace Isolation Bypass via Percent-Encoded Path

Kyverno before 1.19.1 contains a namespace isolation bypass in the apiCall context entry of namespaced Policy resources due to inconsistent path interpretation between validation and execution. A low-privilege tenant can use percent-encoded dot-segments in urlPath to bypass namespace checks and...

BIT-ENVOY-2026-73551 Envoy: Path normalization does not handle dot and dotdot segments with parameters

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's URL normalization does not recognize dot and dotdot path segments when they carry semicolon parameters. A request such as /user/..;foo=bar/admin is therefor...

CVE-2026-86253

A flaw was found in h3, an npm package. An unauthenticated remote attacker can exploit this vulnerability by sending crafted requests to endpoints served by the serveStatic function. On Node.js deployments, the event.url.pathname is not properly normalized, allowing percent-encoded dot segments t...

CVE-2026-85124

A flaw was found in @fastify/http-proxy. This component, designed to proxy HTTP requests, does not correctly validate incoming request paths, specifically failing to account for backslash-based dot-segments. An unauthenticated network attacker can exploit this vulnerability to bypass the proxy's...

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-2026-85124 @fastify/http-proxy vulnerable to prefix escape via backslash dot-segments

@fastify/http-proxy versions before 11.6.2 do not validate proxied HTTP request paths for backslash based dot-segments before forwarding them to the configured upstream. The plain HTTP request handler skips the destination validation that the WebSocket path performs, and the underlying reply-from...
