CVE-2026-59888

A flaw was found in jackson-databind. When Java Records use a PropertyNamingStrategy, an attacker can bypass the @JsonIgnore annotation during deserialization. This allows a renamed JSON key to be assigned to a Record constructor parameter, even if it was intended to be ignored. Consequently, an untrusted client could set internal or privileged components from external input, potentially leading to unauthorized modification or disclosure of sensitive data.

Moderate impact. This flaw in jackson-databind allows an attacker to bypass the @JsonIgnore annotation when deserializing Java Records that utilize a PropertyNamingStrategy. An untrusted client could exploit this to assign values to internal or privileged Record constructor parameters, potentially leading to unauthorized data modification or disclosure. Red Hat products using affected versions of jackson-databind for deserialization of external input into Java Records with PropertyNamingStrategy are susceptible.
