CVE-2026-50135

Description

A flaw was found in Hugo, a static site generator. A regression in the resources.Get function caused it to follow symbolic links (symlinks), which are special files that point to other files or directories. This vulnerability allows an attacker who can place a symlink within a local mount point, such as a vendored theme, to read arbitrary files on the system that are accessible to the user running Hugo. This could lead to unauthorized information disclosure.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Confidentiality,Integrity,Access Control

Technical Impact: Read Files or Directories; Modify Files or Directories; Bypass Protection Mechanism

An attacker may be able to traverse the file system to unintended locations and read or overwrite the contents of unexpected files. If the files are used for a security mechanism then an attacker may be able to bypass the mechanism.

Other

Technical Impact: Execute Unauthorized Code or Commands

Windows simple shortcuts, sometimes referred to as soft links, can be exploited remotely since a ".LNK" file can be uploaded like a normal file. This can enable remote execution.
