CyberRota Analysis

AI-Generated

Prompty versions prior to 2.0.0-beta.2 are vulnerable due to improper handling of file references in markdown frontmatter, which allows attackers to exploit these references to access local files through absolute paths, directory traversal, or symlink escapes. The potential impact includes unauthorized data exposure and system compromise. Organizations using affected versions should prioritize upgrading to the fixed version to mitigate these risks.

Original NVD Description

Prompty is a markdown file format (.prompty) for LLM prompts. Prior to 2.0.0-beta.2, Prompty loaders expanded ${file:...} references in .prompty frontmatter without enforcing that resolved paths stayed within the prompt directory or allowed roots, allowing an attacker-controlled prompt file to read local files through absolute paths, .. traversal, or symlink escapes. This issue is fixed in versions 2.0.0-beta.2.
