CVE-2026-50193: CWE-400: Uncontrolled Resource Consumption in FasterXML jackson-databind
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.
AI Analysis
Technical Summary
jackson-databind versions from 2.13.0 to before 2.14.0 contain a vulnerability classified as CWE-400 (Uncontrolled Resource Consumption). When the service processes deeply nested JSON structures (thousands of levels) using ObjectMapper.readTree() to read into a JsonNode and subsequently serializes the node back to a string, it can consume significant system resources. This can lead to denial-of-service conditions, especially under concurrent requests with relatively small payloads (~2kB for 1000 nested arrays). The vulnerability is resolved in version 2.14.0.
Potential Impact
An attacker can cause denial-of-service by sending deeply nested JSON payloads that consume excessive CPU and memory resources during parsing and serialization. This can degrade or disrupt service availability. There are no indications of privilege escalation, data disclosure, or code execution from this vulnerability.
Mitigation Recommendations
Upgrade jackson-databind to version 2.14.0 or later, where this vulnerability is fixed. Patch status is confirmed by the vendor advisory stating the fix in 2.14.0. No other mitigations are indicated.
