RHSA-2026:40895
Vulnerability from csaf_redhat - Published: 2026-07-16 12:11 - Updated: 2026-07-21 21:12A 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 type parameter of an allowed container. This leads to the loading and instantiation of arbitrary classes, potentially resulting in 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 execution of malicious code. This could result in a complete compromise of the affected system, impacting its confidentiality, integrity, and availability.
