CVE-2026-28807 (GCVE-0-2026-28807)
Vulnerability from nvd – Published: 2026-03-10 21:34 – Updated: 2026-03-12 03:58

Title
Path Traversal in wisp.serve_static allows arbitrary file read
Summary
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.serve_static function is vulnerable to path traversal because sanitization runs before percent-decoding. The encoded sequence %2e%2e passes through string.replace unchanged, then uri.percent_decode converts it to .., which the OS resolves as directory traversal when the file is read.
An unauthenticated attacker can read any file readable by the application process in a single HTTP request, including application source code, configuration files, secrets, and system files.
This issue affects wisp: from 2.1.1 before 2.2.1.
