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 · unedited
An authenticated administrative user who can import or save DataObject class definitions can inject attacker-controlled composite index metadata and trigger unintended SQL execution in the backend. This issue affects pimcore: 12.3.3.

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 analysis
How this class of weakness works · CWE-89

User input is woven into a database query, letting an attacker rewrite the query's logic. From there they can read, alter, or destroy data — frequently the entire database. The reliable fix is parameterised queries (prepared statements), so input is always treated as data and never as SQL.

Recommended fix Moderate confidence

Latest stable pimcore 12.x release (check https://pimcore.com for current version)

  1. 1. Identify your current pimcore installation version by checking your composer.json or installation
  2. 2. Review the changes in GitHub PR #19108 (https://github.com/pimcore/pimcore/pull/19108) to understand the fix
  3. 3. Update pimcore to the latest patch version in your major release line (e.g., latest 12.x stable)
  4. 4. After upgrade, verify the DataObject class import/save functionality works correctly with composite indexes
  5. 5. Test that the SQL injection vulnerability is no longer exploitable by attempting to inject malicious index metadata
Caveat Minor - this is a security patch upgrade, but always review release notes for any deprecation notices
