SiYuan: Path Traversal via Double URL Encoding in `/export/` Endpoint (Incomplete Fix Bypass for CVE-2026-30869)

Summary The fix for CVE-2026-30869 in SiYuan v3.5.10 only added a denylist check IsSensitivePath but did not address the root cause — a redundant url.PathUnescape call in serveExport. An authenticated attacker can use double URL encoding %252e%252e to traverse directories and read arbitrary...

OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. Versions 7.5.0 through 7.15.1 have a configuration-dependent authentication bypass. Deployments are affected when all of the following are true: Use of skipauthroutes or the legacy skipauthregex; use of patterns...

@fastify/static vulnerable to route guard bypass via encoded path separators

Impact @fastify/static v9.1.0 and earlier decodes percent-encoded path separators %2F before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/ do not match /admin%2Fsecret.html, but @fastify/static decodes it to...

GHSA-X428-GHPX-8J92 @fastify/static vulnerable to route guard bypass via encoded path separators

Impact @fastify/static v9.1.0 and earlier decodes percent-encoded path separators %2F before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/ do not match /admin%2Fsecret.html, but @fastify/static decodes it to...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the namespace parameter in the Ruler API endpoint after double URL encoding. An attacker can access arbitrary files by sending specially crafted requests. Details A Directory Traversal attack also known as path...

Emissary has a Path Traversal via Blacklist Bypass in Configuration API

Summary The configuration API endpoint /api/configuration/name validated configuration names using a blacklist approach that checked for , /, .., and trailing .. This could potentially be bypassed using URL-encoded variants, double-encoding, or Unicode normalization to achieve path traversal and...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the validate function in the /api/configuration/name configuration API endpoint. An attacker can gain unauthorized read access to sensitive configuration files outside the intended directory by submitting special...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal in the POST multipart upload process. An attacker can write arbitrary files to any existing directory on the filesystem by crafting a specially constructed URL path containing directory traversal sequences and...

CVE-2026-34523 SillyTavern: Path traversal allows file existence oracle

SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to version 1.17.0, a path traversal vulnerability in the static file route handler allows any unauthenticate...

BIT-MASTODON-2026-33868 Mastodon has a GET-Based Open Redirect via '/web/%2F<domain>'

Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.5.8, 4.4.15, and 4.3.21, an unauthenticated Open Redirect vulnerability CWE-601 exists in the /web/ route due to improper handling of URL-encoded path segments. An attacker can craft a specially encode...

CVE-2026-33868

Mastodon is affected by an unauthenticated Open Redirect (CWE-601) in the /web/* route prior to versions 4.5.8, 4.4.15, and 4.3.21. The root cause is improper handling of URL-encoded path segments, where encoded slashes (%2F) bypass Rails path normalization and are treated as host-relative redire...

h3: Double Decoding in `serveStatic` Bypasses `resolveDotSegments` Path Traversal Protection via `%252e%252e`

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...

CVE-2026-32004

OpenClaw versions prior to 2026.3.2 contain an authentication bypass vulnerability in the /api/channels route classification due to canonicalization depth mismatch between auth-path classification and route-path canonicalization. Attackers can bypass plugin route authentication checks by submitti...

CVE-2026-28807

CVE-2026-28807 affects gleam-wisp wisp; path traversal in wisp.serve_static occurs because sanitization runs before percent-decoding, allowing %2e%2e to decode to .. and read any file the process can access. Affected versions are 2.1.1 &lt;= wisp

CVE-2026-28807 Path Traversal in wisp.serve_static allows arbitrary file read

Improper Limitation of a Pathname to a Restricted Directory 'Path Traversal' vulnerability in gleam-wisp wisp allows arbitrary file read via percent-encoded path traversal. The wisp.servestatic function is vulnerable to path traversal because sanitization runs before percent-decoding. The encoded...

CVE-2025-14728

Rapid7 Velociraptor versions before 0.75.6 contain a directory traversal issue on Linux servers that allows a rogue client to upload a file which is written outside the datastore directory. Velociraptor is normally only allowed to write in the datastore directory. The issue occurs due to...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal due to insufficient sanitization of directory names ending with a "." in the upload process. An attacker can write files outside the intended datastore directory by crafting directory names that end with "%2E". This ...
