Summary

CVE-2026-94636 is a high-severity Data Amplification (CWE-409) vulnerability in Apache Thrift (inferred from references). Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 35th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation partial match

Developer testing and evaluation directly finds incorrect function calls via static analysis, unit testing, and code review.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented development processes, standards, and tools (e.g., compilers, linters) structurally reduces the chance of incorrect argument specification.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles applied during development include correct API usage and interface contracts that stop malformed calls.

SC-6 Resource Availability partial match

Resource allocation controls bound memory/CPU consumption that a data-amplification attack would otherwise exhaust.

SI-10 Information Input Validation partial match

Input validation can reject or limit decompression of data whose expansion ratio exceeds safe thresholds.
