      "value": "PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a table and placing malicious code inside a column identifier. If a superuser calls the k-anonymity function, the malicious code is executed with superuser privileges. The risk is higher with PostgreSQL 14 or with instances upgraded from PostgreSQL 14 or a prior version. With PostgreSQL 15 and later, the creation permission on the public schema is revoked by default and this exploit can only be achieved by a user who was explicitly granted the CREATE TABLE privilege. The problem is resolved in PostgreSQL Anonymizer 3.1.0 and further versions"

      "value": "PostgreSQL Anonymizer contiene una vulnerabilidad que permite a un usuario obtener privilegios de superusuario creando una tabla y colocando código malicioso dentro de un identificador de columna. Si un superusuario llama a la función k-anonymity, el código malicioso se ejecuta con privilegios de superusuario. El riesgo es mayor con PostgreSQL 14 o con instancias actualizadas desde PostgreSQL 14 o una versión anterior. Con PostgreSQL 15 y posteriores, el permiso de creación en el esquema público se revoca por defecto y este exploit solo puede ser logrado por un usuario al que se le concedió explícitamente el privilegio CREATE TABLE. El problema está resuelto en PostgreSQL Anonymizer 3.1.0 y versiones posteriores."
