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
SQL injection vulnerability in cron/find_help.php in Exponent CMS 2.3.9 and earlier allows remote attackers to execute arbitrary SQL commands via the version 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-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.
