🔗 CVE IDs covered (1)

📋 Description

Connect2id Nimbus JOSE + JWT before 10.0.2 allows a remote attacker to cause a denial of service via a deeply nested JSON object supplied in a JWT claim set, because of uncontrolled recursion. NOTE: this is independent of the Gson 2.11.0 issue because the Connect2id product could have checked the JSON object nesting depth, regardless of what limits (if any) were imposed by Gson.

🎯 Affected products2

  • maven/com.nimbusds:nimbus-jose-jwt:< 9.37.4
  • maven/com.nimbusds:nimbus-jose-jwt:>= 9.38-rc1, < 10.0.2
