jackson-databind: jackson-databind: Arbitrary code execution via PolymorphicTypeValidator bypass

A flaw was found in jackson-databind. This vulnerability allows a remote attacker to bypass the PolymorphicTypeValidator PTV when polymorphic typing is enabled and a type identifier contains generic parameters. By crafting a malicious type ID, an attacker can place a denied class as a generic typ...

jackson-databind: Jackson-databind: Security bypass allows arbitrary code execution

A flaw was found in jackson-databind, a library used for processing data. This vulnerability allows an attacker to bypass security controls designed to validate data types. By sending specially crafted input, an attacker can force the system to process untrusted data, which may lead to the...
