FKIE_CVE-2026-32687

Vulnerability from fkie_nvd - Published: 2026-05-12 15:16 - Updated: 2026-07-24 15:17
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in elixir-ecto postgrex ('Elixir.Postgrex.Notifications' module) allows SQL Injection. The channel argument passed to 'Elixir.Postgrex.Notifications':listen/3 and 'Elixir.Postgrex.Notifications':unlisten/3 is interpolated directly into LISTEN "..." / UNLISTEN "..." SQL statements without escaping the " character. An attacker who can influence the channel name can inject a " to break out of the quoted identifier and append arbitrary SQL. Because the notifications connection uses the PostgreSQL simple query protocol, multi-statement payloads are accepted, allowing DDL and DML commands to be chained (e.g. ; DROP TABLE ...; --). The same unsanitized interpolation also occurs in handle_connect/1 when replaying LISTEN commands after a reconnect. This vulnerability is associated with program file lib/postgrex/notifications.ex and program routines 'Elixir.Postgrex.Notifications':listen/3, 'Elixir.Postgrex.Notifications':unlisten/3, 'Elixir.Postgrex.Notifications':handle_connect/1. This issue affects postgrex: from 0.16.0 before 0.22.2.
