Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’) vulnerability in elixir-ecto postgrex allows SQL Injection via the :comment option of Postgrex.stream\/4. An attacker who can influence that value can close the comment delimiter with *\/ and extend the streamed statement with their own clauses, which execute under the connection’s role. Ecto exposes the same option through Ecto.Repo.stream\/2.<\/p>\n
Postgrex appends the comment by concatenating it into the statement text sent in the Parse message, without escaping or rejecting *\/. The option is validated by comment_not_present!\/1 at every other execution point; stream\/4 never calls it. Because Parse accepts a single command, the injection is confined to the streamed statement and further statements cannot be chained.<\/p>\n
