high Tenable Cloud Security Plugin ID 444851

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Prompty is a markdown file format (.prompty) for LLM prompts. From 2.0.0-alpha.1 until 2.0.0-beta.3, the
 @prompty/core TypeScript loader in runtime/typescript/packages/core/src/core/loader.ts used gray-matter
 without overriding executable js and javascript frontmatter engines, allowing an attacker-controlled
 .prompty file with ---js frontmatter to execute arbitrary JavaScript during prompt loading. This issue is
 fixed in version 2.0.0-beta.3. (CVE-2026-53597)

Solution

Update the @prompty/core library and its related packages to version 2.0.0-beta.3 or later.
