CVE-2026-83745— Apache Thrift, Apache Thrift: WebSocket frame decoders allocate the payload buffer from the declared length, not the bytes received (Node.js, D)
Quick assessment
Affected
Apache Software Foundation Apache Thrift
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache Thrift 的 Node.js 和 D 语言绑定中存在因长度参数处理不当导致的漏洞，具体表现为内存分配时使用了过大的尺寸值。 在这两个绑定实现的 WebSocket 服务器传输模块中，系统会直接从帧头中读取负载长度，并立即分配相应数量的字节，而未检查数据是否实际到达。因此，一个仅需约 14 字节的帧即可根据帧头中声明的大小分配任意量的内存。经测试，Node.js 服务器会分配高达 513 MiB 的内存，而 D 语言绑定则会分配高达 2 GiB 的内存。在 Node.js 的情况下，连接在内存分配后

Vulnerability Title
Apache Thrift, Apache Thrift: WebSocket frame decoders allocate the payload buffer from the declared length, not the bytes received (Node.js, D)
Source: CVE Program / CVE List V5
Vulnerability Description
Memory allocation with excessive size value, Improper handling of length parameter inconsistency vulnerability in Apache Thrift
nodejs and D lang bindings.
Both bindings' WebSocket server transports read the payload length out of the frame header and allocate that many bytes immediately, without checking that the bytes have arrived. A single ~14-byte frame therefore commits as much memory as it cares to declare -- measured at 513 MiB against the Node.js server and 2 GiB against the D transport -- and in the Node.js case the connection is left open afterwards, so the frame can simply be sent again.
This issue affects Apache Thrift before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.
