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.

AnalysisAI
Memory exhaustion in Apache Thrift's Node.js and D language WebSocket server transports (all versions before 0.25.0) lets unauthenticated remote attackers commit 513 MiB on a Node.js server, or up to 2 GiB on the D transport, by sending a single ~14-byte frame that merely declares a huge payload length. The transport reads the length out of the WebSocket frame header and allocates that many bytes immediately, before the payload has actually arrived, so an extremely small request causes disproportionate memory growth; in the Node.js case the connection is left open afterwards, allowing the same frame to be resent repeatedly until the service is exhausted or killed. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires the target to run the Apache Thrift WebSocket server transport from the Node.js or D language bindings at a version before 0.25.0, reachable by the attacker over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded availability risk - a resource-exhaustion (memory) denial-of-service flaw, not a code-execution or data-exposure bug. … 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 to Apache Thrift 0.25.0, which the advisory states fixes the issue; because the Node.js binding is distributed via npm and the D binding via its package registry, verify that the resolved dependency version is at least 0.25.0 rather than only bumping a top-level constraint, and rebuild any bundled or vendored copies. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within the next 24 hours, inventory every externally reachable and internally exposed service that uses the Apache Thrift WebSocket server transport from the Node.js or D bindings, confirm the deployed Thrift version (all versions before 0.25.0 are affected), and where the transport is not strictly required, disable it or block it at the load balancer, API gateway, or firewall so it is not reachable from untrusted networks. …
