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."}], "lastModified": "2026-06-27T20:51:09.987", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:fasterxml:jackson-databind:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0D4E698D-DF81-4E00-9173-ABBE3E8D82E4", "versionEndExcluding": "2.21.4", "versionStartIncluding": "2.21.0"}, {"criteria": "cpe:2.3:a:fasterxml:jackson-databind:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5C0F99DE-1DB7-4873-83F9-6CEF8E91F33C", "versionEndExcluding": "3.1.4", "versionStartIncluding": "3.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
