      "value": "Code injection in SQL code generation in Apache Flink 1.15.0 through 1.20.x and 2.0.0 through 2.x allows authenticated users with query submission privileges to execute arbitrary code on TaskManagers via maliciously crafted SQL queries. The vulnerability affects JSON functions (1.15.0+) and LIKE expressions with ESCAPE clauses (1.17.0+). User-controlled strings are interpolated into generated Java code without proper escaping, allowing attackers to break out of string literals and inject arbitrary expressions.\n\nUsers are recommended to upgrade to either version 1.20.4, 2.0.2, 2.1.2 or 2.2.1, which fixes this issue."

La vulnerabilidad afecta a las funciones JSON (1.15.0+) y a las expresiones LIKE con cláusulas ESCAPE (1.17.0+). Las cadenas controladas por el usuario se interpolan en el código Java generado sin el escape adecuado, permitiendo a los atacantes salir de los literales de cadena e inyectar expresiones arbitrarias.\n\nSe recomienda a los usuarios actualizar a la versión 1.20.4, 2.0.2, 2.1.2 o 2.2.1, que corrige este problema."
