Deserialization of Untrusted Data in jackson-databind

  • Disclosed: 30.06.2020
  • Updated: 11.10.2026 12:21

FasterXML jackson-databind through 2.8.11 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 and CVE-2017-17485 deserialization flaws. This is exploitable via two different gadgets that bypass a blacklist.
