jackson-databind is vulnerable to a deserialization flaw

  • Disclosed: 16.10.2018
  • Updated: 11.10.2026 12:21

A deserialization flaw was discovered in the jackson-databind, versions before 2.6.7.1, 2.7.9.1 and 2.8.9, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper.
