ADOdb is a PHP database class library that provides abstractions for performing queries and managing databases. Prior to version 5.22.9, improper escaping of a query parameter may allow an attacker to execute arbitrary SQL statements when the code using ADOdb connects to a PostgreSQL database and calls pg_insert_id() with user-supplied data. This issue has been patched in version 5.22.9.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
