Severity

Important

Scope

40 vulnerabilities in this advisory, including CVE-2026-43870.

CVE-2026-43870

A flaw was found in Apache Thrift. This vulnerability encompasses an origin validation error, improper limitation of a pathname to a restricted directory (path traversal), and improper neutralization of CRLF sequences in HTTP headers (HTTP request/response splitting). A remote attacker could exploit these issues to trigger uncontrolled resource consumption, leading to a Denial of Service (DoS) condition. Furthermore, path traversal could allow unauthorized access to files, and HTTP request/response splitting might enable other web-based attacks.
