CVE-2023-33546: Janino Project Janino

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Janino Project Janino: up to and including 3.1.9
