The 6.x branch is not affected. \n\nExample:\n```java\nExpressionParser parser = new SpelExpressionParser();\nExpression exp = parser.parseExpression(<user-controlled-data>);\n```\n\nIn order to be exploitable, an application is required to accept and evaluate untrusted (user-controlled) SpEL expressions.
