{"id":"CVE-2026-54517","aliases":["GHSA-5hh8-q8hv-fr38"],"url":"https://o3.security/vulnerability/CVE-2026-54517","summary":"jackson-databind: @JsonView bypass for setterless creator properties","details":"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, 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.","published":"2026-06-23T20:47:22.977Z","modified":"2026-08-12T16:41:15.390159Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.00384,"percentile":0.31526,"asOf":"2026-09-04"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","fixedVersion":"2.21.4"},{"ecosystem":"Maven","name":"com.fasterxml.jackson.core:jackson-databind","fixedVersion":"3.1.4"},{"ecosystem":"Maven","name":"tools.jackson.core:jackson-databind","fixedVersion":"3.1.4"}],"fix":{"url":"https://github.com/FasterXML/jackson-databind/commit/5bf23edb4221f7dd2ec8e71ff6d26c61640f261d","label":"FasterXML/jackson-databind@5bf23ed"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54517.json"},{"type":"ADVISORY","url":"https://github.com/FasterXML/jackson-databind/security/advisories/GHSA-5hh8-q8hv-fr38"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54517"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/commit/5bf23edb4221f7dd2ec8e71ff6d26c61640f261d"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/commit/94c5d215b3af1505098c686405d9641f041a9962"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/pull/5969"},{"type":"FIX","url":"https://github.com/FasterXML/jackson-databind/pull/5970"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T16:41:15.390159Z"}}
