{"cve":"CVE-2026-54516","nvd":{"published":"2026-06-23T21:17:02.723","modified":"2026-10-25T23:10:00.167","status":"Analyzed","description":"jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, POJOPropertiesCollector._renameProperties() allows a property with @JsonProperty(\"renamed\") on the getter and @JsonIgnore on the setter to be renamed rather than dropped. With MapperFeature.INFER_PROPERTY_MUTATORS enabled (default), the private backing field is retained; during deserialization BeanDeserializerFactory.addBeanProps() sees hasField()==true, builds a FieldProperty, and makes the backing field writable. An attacker supplying the renamed JSON key writes the backing field directly, bypassing the @JsonIgnore on the setter. This vulnerability is fixed in 3.1.4.","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:L/A:N","score":5.3},"cwes":["CWE-915"],"references":["https://github.com/FasterXML/jackson-databind/commit/c3d56dd25d52319828147c5b9aeabf2d485c250a","https://github.com/FasterXML/jackson-databind/commit/e88cb17006b6af4883b973058f0bb6486e5074af","https://github.com/FasterXML/jackson-databind/pull/5967","https://github.com/FasterXML/jackson-databind/pull/5968","https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-9fxm-vc8v-hj55"],"products":["fasterxml:jackson-databind"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-54516","score":0.00449,"percentile":0.38755,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-9fxm-vc8v-hj55","url":"https://osv.dev/vulnerability/GHSA-9fxm-vc8v-hj55","summary":"jackson-databind's renamed @JsonIgnore'd setters can deserialize via private fields","modified":"2026-09-10T03:50:49.332051665Z","packages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.21.0 <2.21.4"],"fixed":["2.21.4"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=3.0.0 <3.1.4"],"fixed":["3.1.4"]},{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","purl":"pkg:maven/tools.jackson.core/jackson-databind","ranges":[">=3.0.0 <3.1.4"],"fixed":["3.1.4"]}]}],"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).
