Summary

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

From 2.15.0 until 2.18.8, 2.21.4, and 3.1.4, Java Records using a PropertyNamingStrategy can bypass @JsonIgnore because POJOPropertiesCollector._removeUnwantedIgnorals() records an ignored component under its original implicit name before _renameUsing() applies the naming strategy, allowing the renamed JSON key to be assigned to the Record constructor parameter.

This issue is fixed in versions 2.18.8, 2.21.4, and 3.1.4. 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.

Red Hat products using affected versions of jackson-databind for deserialization of external input into Java Records with PropertyNamingStrategy are susceptible. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).

Weakness: CWE-915.

Affected products named by the advisory: Red Hat AMQ Broker 7.13.6; Red Hat AI Inference Server 3.3; Red Hat Enterprise Linux AI 3.3; Red Hat Lightspeed (formerly Insights) for Runtimes 1.0; and 41 more.

Is CVE-2026-59888 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-59888 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.
