MEDIUM

Janino < 3.1.9 - Denial of Service via Expression Evaluator Parameter Name Guessing

Title source: llm
STIX 2.1

Description

Janino 3.1.9 and earlier are subject to denial of service (DOS) attacks when using the expression evaluator.guess parameter name method. If the parser runs on user-supplied input, an attacker could supply content that causes the parser to crash due to a stack overflow. NOTE: this is disputed by multiple parties because Janino is not intended for use with untrusted input.
