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.","published_at":"2026-06-23T20:48:52.730000Z","last_modified_at":null,"cvss_v3_score":5.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-915"],"nvd_references":["https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-9fxm-vc8v-hj55","https://github.com/FasterXML/jackson-databind/pull/5967","https://github.com/FasterXML/jackson-databind/pull/5968","https://github.com/FasterXML/jackson-databind/commit/c3d56dd25d52319828147c5b9aeabf2d485c250a","https://github.com/FasterXML/jackson-databind/commit/e88cb17006b6af4883b973058f0bb6486e5074af"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:37.240342Z","updated_at":"2026-06-28T23:30:54.391983Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"fasterxml","vendor_name":"FasterXML","product_slug":"jackson-databind","product_name":"jackson-databind","version_start":">= 2.21.0, < 2.21.4","version_start_inclusive":true,"version_end":">= 2.21.0, < 2.21.4","version_end_inclusive":true,"cpe23_uri":"cve5:fasterxml:jackson-databind:>= 2.21.0, < 2.21.4:>= 2.21.0, < 2.21.4"},{"vendor_slug":"fasterxml","vendor_name":"FasterXML","product_slug":"jackson-databind","product_name":"jackson-databind","version_start":">= 3.0.0, < 3.1.4","version_start_inclusive":true,"version_end":">= 3.0.0, < 3.1.4","version_end_inclusive":true,"cpe23_uri":"cve5:fasterxml:jackson-databind:>= 3.0.0, < 3.1.4:>= 3.0.0, < 3.1.4"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-9fxm-vc8v-hj55","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/FasterXML/jackson-databind/pull/5967","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/FasterXML/jackson-databind/pull/5968","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/FasterXML/jackson-databind/commit/c3d56dd25d52319828147c5b9aeabf2d485c250a","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/FasterXML/jackson-databind/commit/e88cb17006b6af4883b973058f0bb6486e5074af","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-23T20:48:52.730000Z","label":"CVE published","source":null}]}
