From 2.21.0 until 2.21.4 and 3.1.4, in BeanDeserializer._deserializeUsingPropertyBased, the active-view (@JsonView) filter was applied only to creator properties; the regular property-buffering branch performed no prop.visibleInView(activeView) check. A change making SetterlessProperty.isMerging() return true routed setterless Collection/Map properties through this unguarded path, so a setterless collection annotated with a restricted @JsonView is populated from attacker JSON even when the active view excludes it. This vulnerability is fixed in 2.21.4 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-863"],"references":["https://github.com/FasterXML/jackson-databind/commit/5bf23edb4221f7dd2ec8e71ff6d26c61640f261d","https://github.com/FasterXML/jackson-databind/commit/94c5d215b3af1505098c686405d9641f041a9962","https://github.com/FasterXML/jackson-databind/pull/5969","https://github.com/FasterXML/jackson-databind/pull/5970","https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-5hh8-q8hv-fr38"],"products":["fasterxml:jackson-databind"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-54517","score":0.00384,"percentile":0.32193,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5hh8-q8hv-fr38","url":"https://osv.dev/vulnerability/GHSA-5hh8-q8hv-fr38","summary":"jackson-databind has @JsonView bypass for setterless creator properties","modified":"2026-09-10T03:51:07.997389778Z","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).
