Description
The vulnerability allows a remote attacker to execute arbitrary SQL commands.
The vulnerability exists due to improper neutralization of special elements used in an SQL command in the PostgreSQL query handling for dot-notation field names when processing queries that use dot-notation field names with the sort parameter. A remote attacker can send a specially crafted query parameter to execute arbitrary SQL commands.
The issue only affects deployments using a PostgreSQL database and may also affect queries that use dot-notation field names with the distinct and where query parameters.
