EPSS · scored 2026-10-22

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply nested JSON if (and only if) the service reads deeply nested (1000s of levels) JSON as JsonNode (ObjectMapper.readTree()) and writes out same (or modifided) node using JsonNode.toString(). This can consume significant amount of resources with concurrent relatively small requests (1000 nested arrays is 2kB). This vulnerability is fixed in 2.14.0.

  • WID-SEC-W-2026-2058FasterXML Jackson: Mehrere SchwachstellenDeutsch2026-06-23csaf · cert_bundDE

    Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in FasterXML Jackson ausnutzen, um Schutzmechanismen und Autorisierungsregeln zu umgehen, Daten zu manipulieren, Informationen offenzulegen oder einen Denial-of-Service zu verursachen.

    ### Impact Potential Denial-of-Service when attacker sends deeply nested JSON if (and only if) service: 1. Reads deeply nested (1000s of levels) JSON as `JsonNode` (ObjectMapper.readTree()) 2. Writes out same (or modifided) node using `JsonNode.toString()` which can consume significant amount of resources with concurrent relatively small requests (1000 nested arrays is 2kB). ### Patches Fixed in 2.14.0 via https://github.com/FasterXML/jackson-databind/issues/3447. ### Workarounds Avoid serializing `JsonNode` using `toString()`: use ObjectMapper.writeValueAsString(node)
