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
Camaleon CMS v2.7.0 was discovered to contain a Server-Side Template Injection (SSTI) vulnerability via the formats parameter.

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-94

The application evaluates attacker-influenced input as code, handing them a way to run logic inside the process. Depending on the runtime this can escalate directly to remote code execution. Remediation means removing dynamic evaluation of untrusted input and replacing it with safe, data-driven alternatives.

Recommended fix Moderate confidence

Latest stable Camaleon CMS release above version 2.7.0

  1. 1. Back up your current Camaleon CMS installation and database before making any changes
  2. 2. Identify your current Camaleon CMS version by checking the Gemfile or running `gem list camaleon_cms`
  3. 3. Upgrade Camaleon CMS to the latest stable release above 2.7.0 using Bundler: `bundle update camaleon_cms` or by updating the version in your Gemfile
  4. 4. Run database migrations if any are required: `rake camaleon_cms:migrate`
  5. 5. Restart your application server
  6. 6. Verify the application is functioning correctly and test that the formats parameter no longer executes arbitrary code
  7. 7. Test for SSTI vulnerability using template injection payloads to confirm remediation
