CVE-2026-94658 · Severity: info · Published 2026-10-02

Apache Thrift is a framework that enables client-server applications to communicate across different programming languages. The Lua bindings contain an inefficient algorithmic complexity vulnerability that could degrade performance when processing certain inputs. This may allow an attacker to cause denial of service through resource exhaustion.
