In JDKFromStringDeserializer.NioPathHelper.deserialize, a string bound from untrusted JSON is passed to new URI(value) and then to Path.of(uri). When that throws FileSystemNotFoundException, the code enumerates ServiceLoader<FileSystemProvider> and calls provider.getPath(uri) on the first provider whose scheme matches the attacker-chosen scheme. Untrusted JSON can therefore select and drive an arbitrary registered FileSystemProvider during readValue under a default JsonMapper, and forces provider class loading at the same time. With only the JDK built-in providers (file, jar/zipfs) present, the resolved path is inert and no mount or network I/O occurs; further impact requires a side-effecting third-party FileSystemProvider on the classpath. This affects com.fasterxml.jackson.core:jackson-databind from 2.8.0 before 2.18.10, from 2.19.0 before 2.21.6, and from 2.22.0 before 2.22.2, and tools.jackson.core:jackson-databind from 3.0.0 before 3.1.6 and from 3.2.0 before 3.2.2. Users should upgrade to 2.18.10, 2.21.6, 2.22.2, 3.1.6, or 3.2.2. Binding java.nio.file.Path from untrusted JSON should be avoided regardless of version.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-19032)\n\nAffected packages:\n\n- `tools.jackson.core:jackson-databind >= 3.0.0, < 3.1.6`\n- `tools.jackson.core:jackson-databind >= 3.2.0, < 3.2.2`\n- `com.fasterxml.jackson.core:jackson-databind >= 2.8.0, < 2.18.10`\n- `com.fasterxml.jackson.core:jackson-databind >= 2.19.0, < 2.21.6`\n- `com.fasterxml.jackson.core:jackson-databind >= 2.22.0, < 2.22.2`\n\nPatched in:\n\n- `tools.jackson.core:jackson-databind 3.1.6`\n- `tools.jackson.core:jackson-databind 3.2.2`\n- `com.fasterxml.jackson.core:jackson-databind 2.18.10`\n- `com.fasterxml.jackson.core:jackson-databind 2.21.6`\n- `com.fasterxml.jackson.core:jackson-databind 2.22.2`\n\nSource: https://github.com/advisories/GHSA-wjgm-6hv5-3cvf\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Exploit Intelligence, OpenShift Developer Tools and Services, OpenShift Serverless, Red Hat AI Inference Server, Red Hat AMQ Broker 7, Red Hat Ansible Automation Platform 2, … · no fix planned: Exploit Intelligence, OpenShift Developer Tools and Services, Red Hat Ansible Automation Platform 2, Red Hat Build of Keycloak, … · updated 2026-10-02 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-19032.json)","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
