From 2.8.0 until 2.18.9, 2.21.5, and 3.1.4, in BeanDeserializerBase.createContextual(), per-property @JsonIgnoreProperties exclusions are applied by _handleByNameInclusion(), producing a contextual deserializer whose BeanPropertyMap has the ignored properties removed. The subsequent per-property case-insensitivity block (triggered by @JsonFormat(ACCEPT_CASE_INSENSITIVE_PROPERTIES)) rebuilds from this._beanProperties (the original, unfiltered map) instead of contextual._beanProperties, then overwrites the filtered map — restoring every property _handleByNameInclusion had just removed. The ignored property becomes writable again. This vulnerability is fixed in 2.18.9, 2.21.5, and 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/0e1b0b211f7a53baa62ba2f4c9bd006c7bf4d5fa","https://github.com/FasterXML/jackson-databind/issues/5962","https://github.com/FasterXML/jackson-databind/issues/5964","https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-5jmj-h7xm-6q6v"],"products":["fasterxml:jackson-databind"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-54515","score":0.00443,"percentile":0.38204,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5jmj-h7xm-6q6v","url":"https://osv.dev/vulnerability/GHSA-5jmj-h7xm-6q6v","summary":"jackson-databind has case-insensitive deserialization bypasses per-property @JsonIgnoreProperties","modified":"2026-09-10T03:51:08.069993966Z","packages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=3.1.0 <3.1.4"],"fixed":["3.1.4"]},{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","purl":"pkg:maven/tools.jackson.core/jackson-databind","ranges":[">=3.1.0 <3.1.4"],"fixed":["3.1.4"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.8.0 <2.18.9"],"fixed":["2.18.9"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.19.0 <2.21.5"],"fixed":["2.21.5"]},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","purl":"pkg:maven/com.fasterxml.jackson.core/jackson-databind","ranges":[">=2.22.0 <2.22.1"],"fixed":["2.22.1"]}]}],"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).
