Allocation of Resources Without Limits or Throttling vulnerability in Apache Thrift C++, Java, Go, netstd, Python and Delphi bindings.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.

AnalysisAI
Uncontrolled resource allocation in Apache Thrift versions before 0.25.0 allows remote unauthenticated attackers to exhaust memory, CPU, or worker/connection capacity in services built on the C++, Java, Go, netstd, Python, and Delphi bindings (CWE-770), disrupting availability. The impact is availability-only - no confidentiality or integrity loss - rated CVSS 8.2 under CVSS 4.0, with the 4.0 AT:P flag and the independent CVSS:3.1 assessment (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H) both indicating a specific condition must hold for the allocation to trigger, so exploitation is not guaranteed against every message or deployment. …

Vulnerability AssessmentAI
| Exploitation | Remote unauthenticated exploitation is possible against network-reachable Apache Thrift services (C++, Java, Go, netstd, Python, or Delphi bindings) running a version before 0.25.0, by sending messages that trigger uncontrolled resource allocation (CWE-770). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine availability risk but not a top-tier emergency. … 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 | Primary fix: upgrade to Apache Thrift 0.25.0, which the vendor states resolves the issue, for every affected binding in use (C++, Java, Go, netstd, Python, Delphi), including any vendored or language-packaged copies of the runtime; follow the Apache release announcements at https://lists.apache.org/thread/33otcgbqd27wf6qq810q56znzbomnhg1 and https://lists.apache.org/thread/nxlmlhgsh7fwr4mo1fkhtkw3v266qhcx. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Apache Thrift deployments across the C++, Java, Go, netstd, Python, and Delphi bindings, identify internet-facing and business-critical services, and apply interim controls such as request rate limiting, connection and worker caps, memory/CPU quotas, request timeouts, and availability monitoring. …
