Description PRE-NVD

Disclosed via oss-security. NVD scoring and full description are pending.

AnalysisAI

Uncontrolled recursion in Apache Thrift Node.js library's skip() function enables remote denial of service via crafted protocol messages. Attacker sends specially-crafted Thrift messages triggering deep recursion in the skip() deserialization routine, exhausting stack memory and crashing the Node.js process. CVSS 8.7 High severity with network attack vector requiring no authentication. Disclosed via oss-security mailing list on 2026-04-28 alongside three related Thrift vulnerabilities (C++ JSON OOB read CVE-2026-41607, c_glib dispatch stack overflow CVE-2026-41606, Swift Compact Protocol issue CVE-2026-41605), suggesting coordinated security audit results. EPSS data not yet available for 2026 CVE.

Technical ContextAI

Apache Thrift is a cross-language RPC framework using binary serialization protocols. The Node.js implementation includes a skip() function in its protocol deserialization layer, used to skip over unknown or unwanted fields during message parsing. CWE-674 (Uncontrolled Recursion) indicates the skip() function lacks proper recursion depth controls when processing nested data structures. In Thrift's binary protocols, container types (lists, sets, maps, structs) can be arbitrarily nested-legitimate use cases exist for several levels, but malicious messages with hundreds or thousands of nested containers trigger recursive skip() calls. Node.js V8 engine has limited call stack size (typically 10-15KB), making it particularly vulnerable to stack exhaustion attacks. The vulnerability affects the core protocol parsing layer, meaning any Node.js application using Apache Thrift for deserialization is potentially vulnerable regardless of the specific RPC service implementation.

RemediationAI

Upgrade to patched Apache Thrift version per Apache Security Advisory at lists.apache.org/thread/lb4j0zyd5f3g36cos0wql925przpnwql (specific fix version not confirmed in pre-NVD data-check advisory for Node.js library version). Workaround if patching is delayed: implement message size limits and deserialization timeouts at the application layer to detect and terminate abnormally slow parsing operations, typically by wrapping Thrift deserialization calls with Promise.race() using a timeout (e.g., 5-10 seconds) and enforcing maximum message size (e.g., 10MB) at the transport layer before deserialization begins-note this prevents processing of legitimately large messages and adds latency overhead. Network-level mitigation: restrict Thrift service endpoints to trusted IP ranges via firewall rules or VPC security groups to eliminate untrusted attacker access, though this does not protect against insider threats or compromised clients. For critical public-facing services, consider deploying a rate-limiting reverse proxy to throttle requests per source IP, reducing DoS amplification potential-aware this impacts legitimate high-volume clients and requires tuning per workload.
