Description
A flaw was found in jackson-databind. This vulnerability occurs in the data-binding functionality where properties intended to be ignored are incorrectly restored and become writable again. An attacker could potentially exploit this by providing input that modifies data through these supposedly ignored properties. This could lead to unintended changes in application data, impacting data integrity.
Statement
This is a Moderate impact flaw in jackson-databind where applications enabling case-insensitive property matching alongside per-property @JsonIgnoreProperties may inadvertently expose fields to unauthorized modification. This bypass of intended property exclusions could lead to data integrity issues within affected Red Hat products.
