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
Contributor SQL Injection in Gallery <= 4.7.8 versions.

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 · moderate confidence

SQL injection vulnerability in Gallery CMS versions 4.7.8 and below allows authenticated users with contributor-level privileges to inject malicious SQL queries through unsanitized input fields, potentially enabling unauthorized data access or database manipulation.

MitigationUpgrade Gallery to a version newer than 4.7.8, or apply vendor-supplied patch to remediate the SQL injection. Until patched, disable contributor-level accounts or restrict database permissions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Gallery CMS version
    Locate the installed Gallery CMS version number (typically found in admin dashboard, about page, or version metadata file)
    Affected if Installed version is 4.7.8 or lower
  2. Confirm contributor-level accounts exist
    Access user management panel or user database table to list accounts with contributor-level privileges
    Affected if At least one active account has contributor-level permissions
  3. Verify contributor access to input fields
    Log in with a contributor account and identify input fields that accept user-supplied data (commonly in content creation, comment submission, or profile editing areas)
    Affected if Contributor accounts can submit data to input fields in the application
  4. Check for signs of SQL injection in logs
    Review web server error logs and database query logs for abnormal SQL syntax, error messages containing SQL keywords, or suspicious patterns originating from contributor sessions
    Affected if Logs contain SQL syntax errors or unusual query patterns from contributor-level users

Environment is affected if Gallery CMS version is 4.7.8 or below AND contributor-level accounts exist with access to input fields that could accept malicious SQL queries
