{"cve":"CVE-2026-19032","nvd":{"published":"2026-09-01T04:18:00.433","modified":"2026-09-08T19:29:32.200","status":"Awaiting Analysis","description":"jackson-databind's deserializer for java.nio.file.Path resolves an attacker-supplied URI without restricting the URI scheme. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-470","CWE-610"],"references":["https://github.com/FasterXML/jackson-databind/commit/cc6756b61ed90b6b9227f670e0408d5d9bd48551","https://github.com/FasterXML/jackson-databind/commit/ce26eda3481cd796f76ba4c53ffe1da23b53f166","https://github.com/FasterXML/jackson-databind/commit/d94bb632becfe0ba96926b9909ab06d1f87aad6d","https://github.com/FasterXML/jackson-databind/pull/6129","https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-wjgm-6hv5-3cvf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-19032","score":0.00572,"percentile":0.47313,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wjgm-6hv5-3cvf","url":"https://osv.dev/vulnerability/GHSA-wjgm-6hv5-3cvf","summary":"jackson-databind: Path Deserialization Missing Scheme Allowlist for FileSystemProvider Resolution","modified":"2026-09-28T20:30:05.331167692Z","packages":[{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","purl":"pkg:maven/tools.jackson.core/jackson-databind","ranges":[">=3.0.0 <3.1.6"],"fixed":["3.1.6"]},{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","purl":"pkg:maven/tools.jackson.core/jackson-databind","ranges":[">=3.2.0 <3.2.2"],"fixed":["3.2.2"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.8.0 <2.18.10"],"fixed":["2.18.10"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.19.0 <2.21.6"],"fixed":["2.21.6"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.22.0 <2.22.2"],"fixed":["2.22.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
