CVSS 3.1
5.8 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:LCVE-2025-53864
Medium (5.8). EPSS 1.0% chance of exploitation in the next 30 days. Fixed in com.nimbusds:nimbus-jose-jwt 10.0.2, 9.37.4.
Connect2id Nimbus JOSE + JWT 10.0.x before 10.0.2 and 9.37.x before 9.37.4 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.
