CVE-2026-25758
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSpree is an open source e-commerce solution built with Ruby on Rails. A critical IDOR vulnerability exists in Spree Commerce's guest checkout flow that allows any guest user to bind arbitrary guest addresses to their order by manipulating address ID parameters. This enables unauthorized access to other guests' personally identifiable information (PII) including names, addresses and phone numbers. The vulnerability bypasses existing ownership validation checks and affects all guest checkout transactions. This vulnerability is fixed in 4.10.3, 5.0.8, 5.1.10, 5.2.7, and 5.3.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application fails to correctly restrict what a user can do or reach, so functions or resources are available to people who should not have them. Attackers simply probe for the paths where the check is missing or wrong. The fix is to enforce access-control decisions consistently on every request, evaluated against the acting user rather than assumed from context.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.10.35.0.85.1.10
Upgrade to 4.10.3 (for 4.x) or 5.0.8/5.1.10/5.2.7/5.3.2 (for 5.x) depending on your current major version
- 1. Identify the current Spree version in your Gemfile (e.g., gem 'spree', '~> X.Y.Z')
- 2. Run `bundle update spree` to update to the latest patch version in your current major line
- 3. Alternatively, specify the exact fixed version: for 4.x use 4.10.3, for 5.0.x use 5.0.8, for 5.1.x use 5.1.10, for 5.2.x use 5.2.7, or for 5.3.x use 5.3.2
- 4. Run `bundle install` to update dependencies
- 5. Run database migrations if any: `bundle exec rails db:migrate`
- 6. Test the guest checkout flow to verify the address access control fix is working correctly
- 7. Deploy the updated version to production
