GHSA-VFP3-V2GW-7WFQ Echo: Encoded slash (%2F) bypasses route-level protection and exposes static files

Summary Echo's router and static file handler disagree on URL path decoding. The router matches routes using the raw encoded path preserving %2F as-is, while StaticDirectoryHandler unescapes %2F to / before resolving filesystem paths. This allows an attacker to bypass route-level access controls...

CVE-2026-71209 audiobookshelf - %2F Encoding Discrepancy Bypasses Cover/Image Auth Exemption Regex, Enabling Unauthenticated Path Traversal

audiobookshelf's authentication-exemption check server/routers/Auth.js matches unauthenticated-allowed GET routes against req.path via a regex requiring a literal /items/:id/cover or /authors/:id/image shape, where req.path retains %2F sequences URL-encoded. CacheManager.handleCoverCache then joi...

GHSA-QCXP-GM7M-4J5V Quarkus: Authentication/Authorization Bypass via Advanced Path Normalization Vulnerabilities

Quarkus HTTP path-based authorization policies can be bypassed using encoded semicolons %3B to smuggle matrix parameters past the security layer, and using encoded slashes %2F or backslashes %5C to access protected static resources. This is a distinct issue from CVE-2026-39852, which addressed on...

PYSEC-2026-2877 Pipecat: Path Traversal in Pipecat Runner `/files` Endpoint — Arbitrary File Read via `%2F`-Encoded Separator

Summary A path traversal vulnerability exists in Pipecat's development runner src/pipecat/runner/run.py. When the runner is started with the --folder flag, it exposes a GET /files/filename:path download endpoint. The filename path parameter is concatenated directly onto args.folder with no...

Interpretation Conflict

Overview @fastify/middie is a Middleware engine for Fastify Affected versions of this package are vulnerable to Interpretation Conflict via the path parameter handling process. An attacker can gain unauthorized access to protected route handlers by sending a crafted URL containing an encoded slas...

CVE-2026-14198

@fastify/middie versions 9.1.0 through 9.3.2 decode the encoded slash %2F inside path parameter values before matching middleware paths, while Fastify's underlying router preserves the encoding during route lookup. The two layers disagree on the canonical request path, so the middleware fails to...

CVE-2026-14198

The CVE-2026-14198 entry concerns @fastify/middie versions 9.1.0–9.3.2, where encoded slashes (%2F) in path parameter values are decoded by middie but not by Fastify’s router during route lookup. This mismatch lets a crafted URL bypass middleware-based security (authentication/authorization/rate ...
