Remote unauthenticated malformed JSON (AV:N/AC:L/PR:N/UI:N); infinite loop yields A:H, and prototype pollution warrants at least I:L, which the vendor vector omits.

Loop with unreachable exit condition ('infinite loop'), Improperly controlled modification of object prototype attributes ('prototype pollution') vulnerability in Apache Thrift NodeJS bindings with TJSONProtocol.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.
Articles & Coverage 1
AnalysisAI
Denial of service and limited integrity tampering in Apache Thrift before 0.25.0 stem from a combination of an infinite loop (CWE-835) and prototype pollution in the Node.js bindings when the TJSONProtocol deserializer parses crafted JSON. Any application exposing a Thrift service built on the Node.js library with TJSONProtocol enabled on an untrusted, attacker-reachable input path can be driven into an unreachable-exit loop that hangs the process, with secondary risk of object prototype attribute manipulation altering application state; the vulnerability is reachable unauthenticated and without user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N, availability High, integrity Low) and the vendor rates it 8.7. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target application to use Apache Thrift's Node.js bindings specifically with the TJSONProtocol deserializer and to process attacker-reachable, untrusted JSON input; services using other protocols (e.g. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded-impact priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade Apache Thrift to version 0.25.0, which resolves both the infinite loop and the prototype pollution in the Node.js TJSONProtocol path; Thrift consumers should bump the thrift npm dependency (and any language packages sharing the release train) to 0.25.0 or later and redeploy the Node.js service. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all applications using Apache Thrift Node.js bindings with TJSONProtocol enabled and apply the vendor-released patch version 0.25.0; if immediate patching is not feasible, disable TJSONProtocol or restrict untrusted input paths to reduce exposure. …
