Is CVE-2026-54513 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-54513 is not in the CISA KEV catalog (checked ) and no tracked advisory for it reports exploitation. That is not proof the vulnerability cannot be exploited.

How do I fix CVE-2026-54513?

Upgrade to a fixed release named by the vendor:

  • Red Hat: 2.18.8, 2.21.4, 3.1.4, jackson-databind, cryostat/cryostat-reports-rhel9:4.2.0-13, cryostat/cryostat-rhel9:4.2.0-13
  • Upgrade to version 2.18.8, 2.21.4, or 3.1.4 or later to address this vulnerability. If upgrading is not immediately possible, remove BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() from the application’s ObjectMapper configuration to eliminate the affected deserialization path. Rebuild and restart the application to apply the configuration change. As an additional mitigation, disable polymorphic deserialization of untrusted data where possible by avoiding or removing default typing features such as activateDefaultTyping() or enableDefaultTyping(). When polymorphic deserialization is required, restrict allowed subtypes using a strict whitelist of trusted application packages and avoid broad or permissive type validation rules. (Red Hat)

    High [CVE-2026-54513] Security bypass allows arbitrary code execution

    CVE-2026-54513Source published Source updated

    jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4, BasicPolymorphicTypeValidator. Builder.allowIfSubTypeIsArray() allowlists any array type based only on clazz.isArray(), without validating the array's component (element) type against the configured allowlist. A PTV built with allowIfSubTypeIsArray() plus an explicit concrete-type allowlist therefore still permits EvilType[] even though EvilType is not allowlisted. When Jackson deserializes the elements and no per-element type IDs are present, it instantiates the component type directly with no further PTV check, bypassing the allowlist. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4. A flaw was found in…
