What is CVE-2026-27747?

The interface_traduction_objets plugin for SPIP, versions prior to 4.3.3, contains an SQL injection vulnerability that could allow authenticated attackers to exploit the id_parent parameter. This vulnerability occurs as the plugin directly concatenates user-supplied input into SQL queries without adequate input validation or parameterization. An attacker with editor-level privileges could potentially manipulate backend database queries, leading to unauthorized data disclosure or modification, and may even trigger a denial of service, depending on the database configuration.
